I'm going to be presenting the Perl Teach-In in Birmingham on Monday 31st March as part of UKUUG's Spring 2008 Conference. The talk will be (lightly) updated from the one I gave at the BBC last summer.
This tutorial won't be free. As I understand it, the class will only be open to people who are registered at the conference, but I don't currently know how much that will cost or whether you'll be able to buy a ticket for just the tutorial day. I'm sure more information will appear on their web site soon.
I should start looking in to running the Teach-In in London again.
