Thank you. The person that did our theme has always said that running a forum from a plug-in is not a good idea. So, I have emailed him to see if he sees any compatibility issues with this plug-in. But, I assume that since Buddy Press is from the people at WordPress, it should work fine.
Thank you for your comments. They are very helpful. So, this plugin (https://wordpress.org/extend/plugins/bp-template-pack/) adds all of the functionality to my existing blog with no other files being installed? I won’t have to install another wordpress for BP, or anything?
