Definately a good idea, va!n.
So, each thread can be first used as an announcement. Then ppl
can post if they go to a certain party or not. Maybe they can talk
about car-/travel-sharing. Or talk about meeting each other at the
party.
When the party is over and someone of this forum has attended the
party - he could write a little report about the party or even post
some pictures.
I like the idea ...
