Hello!
I clicked the link in steam to become part of the OTG Steam group and it brought me to a page that was “private or no longer active” - I was wondering if someone could check on those links and make sure they are connecting to the expected page here at the forums. 
Thanks!

The link is working fine, but the group was made private because of some idiotic spammers.
You’ll have to ask someone to add you (of course I don’t remember who now… Revz or TNT?)
