The wish to have regular meetings has been brought up by a few people in private conversations with me. I think they can work as long as we follow a simple set of rules. The meetings will take place in the #phpbb-dev channel on FreeNode IRC.
All topics of discussion need to be posted ahead of time. We won't have a general status meeting. If you want to discuss something, put it on the agenda. Each item will be discussed at most 10 minutes, with the goal of deciding how to continue work on the subject. If long discussion is necessary it can be had in a smaller group on IRC at a later time or in the respective area51 discussion topic. The meeting will be at most 1 hour long. So only up to 6 agenda points per week are allowed.
To decide on a regular time most of us can make it every week I've created a doodle. It only contains times that I can make it, to make sure I'm always present during these meetings. Please select the days of the week and time you can typically attend an IRC meeting: http://www.doodle.com/tcppphqbrd35ufhf
The first meeting will take place next week. I will create a topic for the agenda once we've picked a date.
