Absolutely. Anyone from North Carolina on up, and West Virginia and East is welcome. I think the early events have been scheduled for the Maryland/Delaware area because A: that's where the people organizing them are from, and B: they're somewhat more central so that anyone travelling to get to it is travelling about the same distance/time. If folks from Philly/South Jersey and folks from Virginia come to Baltimore, that's about halfway for either extreme. If we did something in Philly or Hampton Roads, most folks would be driving for 3+ hours to get to it, making it hard to do in just one day.
In regards to the email, I will gladly send my email address to anyone organizing the mailing list, or anyone who wants it via PM, but I don't want to post an email address on an open forum like this- that's an invitation to get spam.
