Best 'Group' website to set up for a Grad Reunion?

[jory29]

I tried using the Yahoo Groups but it is so messed up - no one seems to be getting their invites, and if they do, it states they are 'not a member'. etc. etc.

Please tell me - the best, free, group website that I can set up so that we can post messages back and forth, etc.

Thanks!! :)
