Hi, mscbryk. Love your title.
The stats page shows the most online for today was 19 (probably from early this morning when you were here), so along with 13 guests there must've been 6 logged members. Nineteen is the high for October and also occurred 2 weeks ago, though I can't give you a breakdown of guests vs. logins from that other date. As to what's bringing them in, I'd like to think it's MB's fantastic graphics.
Have a happy Halloween!
