Hi jamochawoke,
That would be fantastic if you can help out. I'm familiar with some stuff you've done in the past so it's a no-brainer to welcome you to the team. If you can drop by our forums here, that would be ace. You will need to set up a profile if you're new to the site, of course.
That's a wonderful portfolio btw. We could use you for all sorts but we're trying to hold back on some of our own ambitions and to prioritise things for purely practical reasons....and as you have indicated, it's best to take one step at a time and not overcommit. Therefore, quests remain the singlemost important things right now and that's where I think your talents would be best used. Just fyi, quests would be followed by a few bits and pieces of scripting. Thereafter, if you have the time, there are some very interesting projects to work on such as the Sload and Sarpa creatures. Koniption has wanted to get this stuff done for some time but has struggled to balance her workload with RL. Some things, however, we may have to leave out for the beta release.
Personally, I'm more than happy with getting some more quests on the go so I'd be delighted and grateful to have you onboard. I hope to see you on our forums soon. I'll be back on there tomorrow.
EDIT - Thanks to syscrusher for the encouraging comments too.
