Hi, Dave.
If I haven't said it already, welcome to the team.

Great introductory post - just the sort of thing which will help ppl know what they can tap you for! I know you're already doing some sterling work helping out with Paul A's revision of AdventureScape.
Generally, most people here just start their own projects and post back about progress as and when it's made. As you're already doing, if you see anything you think you can help with, just dive in and offer wherever you can. Every now and then ppl drop out test builds of stuff but don't always get feedback - if you get the chance to play any of those and drop in your thoughts, every little helps. That suggestion, of course, goes for anyone!
Ignoring the production side, the one thing we are really missing here is more gfx skills - Dave J has been overloaded with requests for help, for well over a year now. We may have to try asking out in other communities again for that.
There's also nothing wrong with having a security expert looking over our little communities - that's already proven helpful so far.

Sam.
