The WordPress Database Reset plugin allows you to reset the database back to its default settings without having to delete the site and recreate it.
Useful tool for theme and plugin developers who often have to clean up the mess and start over.

WPMU Database Reset

Clean up a single site in a WP network, by removing all posts, comments, terms and media files. A clean slate for the site.

Allows specifying the URL of an image to use as the BuddyPress default group avatar. This makes it easy to distinguish groups from members who are using the mystery man default user avatar. The avatar scales from full to thumb as per your theme settings. It works in all situations (activity stream, groups, forums, directory, etc). Upload your image to somewhere within your theme and drop the full URL in the options screen. Not yet working for multisite/network install.

BuddyPress Group Default Avatar

Adds a default group avatar to BuddyPress. Configure the image URL via the option page.
