Joe Ferguson has posted an interesting idea to help build more community around the various PHP user groups all around the world: a sticker exchange.

I started a thread on the PHP UG Admins email list of doing a User Group sticker exchange and the idea took off pretty quickly. The idea is that user groups that want to participate send stickers to a central location. Stickers are then broken up into packets where every group that sent stickers will receive a packet of stickers from all the other user groups. The goal would be for every user group to send ~50 stickers (Some are sending much more).

Different people in different regions are working on handling the distribution to other local user groups (like Michelangelo Van Dam and Francesco Fullone). If you're a user group, have some stickers and would like to participate, you can sign up using this form and one of the organizers of the exchange will be in touch with you shortly.
