Receive Buddy Press Avatar error

With the Blogs-MU theme, I receive the following message with buddy press:

*ERROR MESSAGE COPIED HERE ==>>

BuddyPress has it's own avatar system. The Avatars plugin functions have been deactivated. Please remove the files.

END OF ERROR MESSAGE COPY.

So I have communities installed because I think it is kind of cool to be able to have unseen communities and such.

BUT, to get rid of this error message, I have to make inactive the avatars plugin.

Do I NEED to have avatars for community to work?

Thanks for letting me know. I don't know if I have a problem with cache or not, but it seems to be working okay. Why in fact is avatars needed for communities to work? Will something happen down the line?

Thanks.
