UK only...
Calling everyone in the UK who's got something to publicise or wants to know what's on:If you haven't been there yet, go to http://www.gig-guide.org, take the trouble to figure out how the system works and put your gigs, or venue into the system. And/or look to see what's on soon in your area.
And if you have any experience of web-based databases, try and think of some suggestions to make it easier to use... :-)
BTW, a list of the next fortnights gigs from that system is posted to uk.music.folk every week.
