There has been little response to Carl's post about not being able to present tomorrow night.
Should we stay or should we go?
(I mean, stay with tomorrow night or go to the following Tuesday - probably not what the Clash were singing about.)
Anyway, if we're staying with tomorrow night, I can give a technical talk about using the Migrate module. I've been hot and heavy for the last couple weeks migrating a vBulletin forum to D7, and I can talk to the specifics of writing mapping code between them.
