Re: 4 Request
Hello
Point 4 is a standard WPMU option and can be found in the Site Options panel of the admin interface.
Photo albums are something that will become a part of BuddyPress eventually (i.e. don’t hold your breath). There is an interim plugin you can use which provides a photo gallery to BuddyPress. I haven’t used it myself but you can find it on https://buddypress.org/extend/plugins/.
The big problem I can see with point 2 is that you are inviting spammers and vandalism in to your site.
