Yep, that RSS feed looks like the business. I'd guess there is some way of making it interwork with Twitter, too. (I'm too new to twittering to know how).

I've started hash-tagging my tweets, following a suggestion from somebody on Footstompin. I'll get more systematic about that when I know all the implications.

Maybe our attitudes to maps are to do with material culture. I'm expecting hardly anybody to travel to a session by car - that's the norm in British cities. So a map is secondary, something you can find for yourself on Google or Multimap if you want one. In a place where you're always going by car you'll want a map up-front.
