I'm thinking POF is a very clicky group who don't really welcome new people
that's absurd.
a few people know each other *because* they attend the events...they haven't ALWAYS known each other.
i'm sure your suggestion of more/bigger signage will be taken to heart, it's a good idea.
it can totally be uncomfortable walking into these situations...it might pay to contact someone else who is signed up next time & arrange to meet them outside so you can go in together, then it's less awkward for at least two of you :)
glad some of you were able to get out & have a good time!
