Actually, due to the 8 time zones we span, plus the various work/sleep times everyone has, it can be a 24 hour/day thing. It varies, but noon-midnight US Eastern is generally the most active times, though there is a small contingent that goes to about 4AM. Just pop on and say "hello?".
When you get all set up, let me know.
We tend to have fun there. Not always horror talk, but a good way to get to know the members.
