Last time I followed the install instructions for a plugin that said to use the /mu-plugins/ folder, I was told that is pretty much being depricated and to simply install as usual.
Before I go to the trouble to set this up, can you tell me if Communities still uses the "old way" -- as per the installation instructions -- or if I just upload it as usual in the plugins folder?
In either case, do the messaging, avatars, and communities plugin need network enabling? Also, I see both Avatars for Multisite and Avatars (BBPress) plugins. Which one do I need?
