You can sign up for the May 2007 edition of the Geek Dinner now, and add what you'd like to contribute to the discussions by adding an offered talk or ask others to contribute by adding a requested talk.  So far, it looks like we're going to hear about Ruby on Rails by Nick Coyne, some sort of Python propaganda from Bryn (possibly on generic functions, which are pretty geeky) and/or I, and about chess as a social medium offered by Tania.

You can also help suggest where the dinner will be - check out the list of venues under consideration for this and future events, and add your suggestions to them.  Also, check out and maybe modify the preferred characteristics of the venues for events.  If you have particular wants (are a vegetarian, vegan, or otherwise meal-fussy, or are allergic to stainless steel), you can help make sure you're catered for.

(Oh, and it you happen to know of a company that wants to sponsor the wine or something else, add that too.)
