Mentions is what I would have done.

I've never used Reddit, so it definitely wouldn't be easier for me to access since I'm on Facebook throughout the day already, but I'm not sure what you mean by more private, unless you simply mean greater anonymity? (You can set a Facebook group to secret and then nonmembers cannot see who is a member nor can they see what is being said therein, it's like it doesn't even exist to those on the outside.)
