hi
For your first question, you may want to try this plugin
https://wordpress.org/extend/plugins/bp-registration-options/
checkout this thread too
https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/moderate-members/
For the second, yes, It is possible. Just go to SiteAdmin->Options and select the radio box which says only logged in users can create blog.
PHp5 may be an issue, better why not ask your server adminstrator to upgrade.
Thanks for your response Brajesh – I’ll check these out
for the second…. if I select only logged in users can create new blogs this also disables new user registration completely.
Yes I need to have the host upgrade to PHP5 but I have a number of sites on the account and I just don’t have time right now to do any debugging if things break right now.
There is a hack to core BP files which can be turned into a plugin (hint, hint) which works in BP 1.2.3 and WPMU 2.9.2 …
sigh… like a number of plugins the bp-registration-options won’t activate
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /…../clubfootclub.org/community/wp-content/plugins/bp-registration-options/bp-registration-options.php on line 23

For signups, please select the box which says user and blogs can be created.
To disable blog creation by non logged in user, put this code in your theme’s functions.php or bp-custom.php
Here is the code on pastebin(current forum has trouble posting code, so i posted it there).
http://bpdev.pastebin.com/1AyszwQ7
And the issue with bp-registration-options seems to be of PHP5.
@mercime – that hack you linked to is totally unnecessary! It is possible to use filters to achieve the same result. The same method was brought up in the IRC room a few days ago. It is actually quite a nice way around the problem 
excuse me r-a-y what is the IRC room? could you give me a link?
@r-a-y I have no idea where to begin with this…. I guess I’ll give the core hack a try
thanks
@dandelionweb
function my_redirect_activation_email()
{
return get_site_option( "admin_email" );
}
add_filter('bp_core_activation_signup_user_notification_to', 'my_redirect_activation_email');
Add this to wp-content/plugins/bp-custom.php or your theme’s functions.php file.
@dandelionweb
Try using the post snippet I posted above.
Thanks so much @r-a-y that code worked….
I’m really struggling to find my way around – I’m experienced with WP but not with WPMU or BuddyPress structure. How do I change this text?
Sign Up Complete!
You have successfully created your account! To begin using this site you will need to activate your account via the email we have just sent to your address.
found it I think… wp-content/plugins/buddypress/bp-themes/bp-default/registration/register.php, line 225,
THANK YOU! THANK YOU! THANK YOU!
So all I had to do was add the following two code snippets to my /wp-content/plugins/buddypress/bp-themes/bp-default/functions.php file and both these issues are fixed! Next step will be upgrading to php5.
/*redirect activation email to admin for approval*/
function my_redirect_activation_email()
{
return get_site_option( “admin_email” );
}
add_filter(‘bp_core_activation_signup_user_notification_to’, ‘my_redirect_activation_email’);
/*disable blog signup for non logged in member*/
add_filter(“wpmu_active_signup”,”bpdev_check_current_users_blog”);
function bpdev_check_current_users_blog($active_signup){
global $current_user;
if( !is_user_logged_in() )
return “none”;
else
return $active_signup;//if the user is logged in, do not change the site policies
}
@dandelionweb
It’s better to make your changes in a child theme. This way your changes will not be overwritten when you have to upgrade BP.
The /*disable blog signup for non logged in member*/ code from @sbrajesh didn’t work… it didn’t remove the create a blog from the signup page.. I got a spam blog within minutes.
ah well that’s it for this rainy Sunday afternoon…. When I get some time next I’ll start but updating to php5 and then I’ll check back with the forum. Thanks everyone!

@sbrajesh and @r-a-y, it was the bad bad mercime who added the link to the hack. i promise never to let my alter ego do it again
the hack adds “the new users’ e-mail address to the e-mail with the activation link. This way you’ll know which activation link belongs to which user.” This is really needed!
Is there another line to add to functions.php that will add the email address?
Actually what we need is a plugin that creates a pending membership panel in the admin so you can go in and active or mark as spam… just like comments!
