Well... I'll say a few things... first, if you are so jaded as to be a pain in the ass to work with then no, I don't think we want you.
That said, I am a very hands-off project leader. I think Shadowspawn can attest to the fact that when someone is put in charge of a sub-task, I give them almost complete control over the task in question. If they want my help or my opinion I give it otherwise as long as they stay within the design parameters they can do what they feel is necessary.
This also means that I expect them to do/finish what they have started. Most people who join mod teams do not finish what they start (And some don't even start)
As far as a dedicated sound engineer, yes... I would very much like one. The sound in wfa was one of the worst things about the mod. We had to keep the old voice com waves because we couldn't find any good voice talent. That sucked.
