Availability of Speaking Slots, and a Shameless Plug

First the shameless plug.  I've just released a rails application that I'm very excited about called Devalot.  It's a social networking app for software development projects akin to Trac or Collaboa.  I have it running at http://software.pmade.com/ if you want to check it out.

Now that I've released Devalot, I have a few extra cycles so I'd like to take on one of the next available speaking slots for the group meetings.  I have a few topics in mind:

* Rails Gotchas: Edge cases where the rails magic makes it hard to get things done

* An introduction to plugins I haven't yet released for tagging, forms and interactive table generation

* Random Ruby topics from the audience?  Sounds fun to me.
