I am willing to participate as time allows. Life has been a bit hectic of late, nothing big really, just wedding plans, looking for a new house, you know regular stuff. :)
Quarterly I think would be reasable.
I'm central US, so time of day isn't that big of deal for me.
I'm willing to dial long-distance. I'm not setup on Skype, but would be willing to do that, too.
