(New username for obvious reasons)
We have a SIF group going for a while for DDF friends. There may be others who'd be interested in joining but we obviously can't go around asking people. If you would like to join PM me here or email me anonymously at sifonddf@gmail.com and we'll take it from there.
This group is for SIF only, and not all SIF situations will be a good fit. We'll see once you email and hear a bit about you.
Also, this is intended for friends who already know each other from DDF. If you only have a few posts etc., it just won't be a comfortable situation for anyone. It's not personal, but the group is probably not for you.
