A quick note / plea to submitters -- it really, really helps if you leave a correct email address when submitting. I frequently (read: several times a week) need to ask a follow-up question or two before adding your submission. If I can't get hold of you, and there's not enough info to go on, your night never gets posted.
For example, if the person who submitted Sarah's Cafe in Lancaster, PA happens to see this, drop me a line -- I need to know some specifics about the schedule there.
Which brings up another helpful point -- if the only schedule information you have is "call for dates" or "check the web site", I can't add you to our listings. No dates means you never show up on the calendar, so there's not much point in adding the night (about 90% of our visits are to the calendar).
