The big problem with regular and scheduled IRC meetings is timezones. We have typically had problems even scheduling meetings for the 5 directors, since they span Australia, Finland, India and the US (until recently we also had a very active member from Germany). The only way to schedule a meeting for all concerned to be available is to choose some unlucky subset to have to come after midnight or in the wee hours of the morning. This usually limits us to weekends, and weekends where everybody is free are relatively rare.
I suppose we could have a system of two meetings per week, with one optimised for each hemisphere or something like that.
For the record, there is usually a lot more discussion happening on the forums. You have come at a relatively rare time where a lot of the directors are tied up IRL so things are a bit quiet.
With regards to division of labour, if people give us an area in which they have at least some experience, we can typically point them in a useful direction. If you don't have any knowledge or experience in directly applicable areas, the best bet is probably to tell us which parts of which projects you find most interesting and we can help you start teaching yourself relevant stuff to contribute to that area.
