Nothing formal, nothing too untoward, a little chit-chat, no Facebook, and perhaps the odd discussion about PHP.
The reason we believe you'll want to come along and talk is that TalkPHP IRC loves you. It loves everybody. It's not particular. Everybody needs a hug from time-to-time, and TalkPHP IRC is only too happy to accommodate.
(TalkPHP IRC loves being venerated, deified, idolised and lionised. Nothing is for free in this world, sunshine!)
