BuddyPress.org

Hey guys!
I’m new to Buddypress and I was wondering if somebody could give me a hand with this one.
What I’m trying to do is to have the auto-generated group slug use the group id instead of its name. The thing is that my users might (and in most cases will) use cyrillic letters in the group names.
I assume this could be implemented with the help of action hooks but due to the lack of experience and documentation I can’t do it myself.
Thanks.
