You can set the number of blog you would like to allow.. its not mine, just wanna share it..

– Aron

EDIT: to set the number of blogs, proceed to Site Admin/Options/ then look below..

I would do this by going into /member-themes/buddypress-member/blogs/create.php and doing…

<?php if ( bp_blog_signup_enabled() ) : ?>

<?php

global $bp;

$blogs = bp_blogs_get_blogs_for_user($bp->loggedin_user->id);

if ($blogs['count'] != 9)

{

bp_show_blog_signup_form();

}

else

{

?>

<div id="message" class="info">

<?php _e( 'Limit nine blogs per member. If you would like another, please contact an Admin for assistance.', 'buddypress' ); ?>



</div>

<?php

}

?>



<?php else: ?>



<div id="message" class="info">

<?php _e( 'Blog registration is currently disabled', 'buddypress' ); ?>



</div>



<?php endif; ?>

Just remember not to overwrite the member theme if you do a BuddyPress update.

OK people this seems to work. This requires modifying the member theme since I didn’t find any actions in bp to hook this into so here goes:

In the member theme the file:

/buddypress-member/blogs/create.php

There is this chunk of code:

<?php if ( bp_blog_signup_enabled() ) : ?>

..(some other stuff here)..

<?php else: ?>

<div id=”message” class=”info”>

<p><?php _e( ‘Blog registration is currently disabled’, ‘buddypress’ ); ?></p>

</div>

<?php endif; ?>

Replace the ..(some other stuff here).. with this:

<?php

global $bp;

$blogs = bp_blogs_get_blogs_for_user($bp->loggedin_user->id);

if (!$blogs)

{

bp_show_blog_signup_form();

}

else

{

?>

<div id=”message” class=”info”>

<p><?php _e( ‘Limit one Blog per member’, ‘buddypress’ ); ?></p>

</div>

<?php

}

?>

This is the entire little create.php file in pastie: http://pastie.org/396083

This was a: “quick ya we should have that and I’ve got to get to the store and get some boxes because I’m moving from Michigan where we have a snow storm today and Virginia where I’m moving to comes to a screeching halt when they get 1″ of snow and I gotta run now” solution.

When I get back from the store I’ll help clean up the damage this might cause. This does work for me in a quick test.

It works for the main blog too, thought the search function isn’t all that useful given there would only be a single blog but all the other functions work with the main blog.

All you’d need to do to get this setup is to change the default role for the main blog from subscriber to contributor and disable blog registration. Also, you may want to hack at the code to remove things such as the blog directory, the list of user blogs, etc. but this is optional.

There is only an option to turn off the adminbar for logged out users. Yes/No for them. Otherwise it’s Yes for everywhere in mu. The adminbar gets generated at every page load in mu. You could disable it completely by default someplace in code and then in the pages that you want it to appear on, enable it before the wp_head() call that your theme makes in header.php

bp registers its need for attention by the calls:

add_action( ‘wp_footer’, ‘bp_core_admin_bar’ );

add_action( ‘wp_head’, ‘bp_core_add_css’ );

You could un-register these calls someplace like functions.php in your theme to turn off the adminbar globally:

remove_action( ‘wp_footer’, ‘bp_core_admin_bar’ );

remove_action( ‘wp_head’, ‘bp_core_add_css’ );

Then in your theme, on the specific pages you want to show the adminbar register the adminbar again before the call to wp_head():

add_action( ‘wp_footer’, ‘bp_core_admin_bar’ );

add_action( ‘wp_head’, ‘bp_core_add_css’ );

In your theme you’ll have to add some logic in header.php to detect what page is being displayed and make the event registration calls.

So, in functions.php un-register the calls and in header.php before wp_head() re-register them. They’ll get turned off again when functions.php loads the next time and the sequence starts again.

I should note, though, that the “Creat a Blog” function doesn’t work, it’s just a link to a page that says registrations are disabled.

Right, that’s the only downside. I only disabled it temporarily, which is why I still installed the blog component but if you never intend on allowing blogs not having it installed is probably for the best.

I still installed bp-blogs, but disabled registrations and it worked perfectly.
