There is also the code camp this Sunday in Auckland, at which
I'll be presenting on Domain Specific Languages, with a
side-order of writing Domain Specific Languages in Boo. 
I'll post about that tomorrow, and maybe include a little more
detail about what I hope to cover.

We'll be meeting at the usual time of 11:30am @ Garrisons, Sylvia
Park, Thursday 10th September - and the topics above are just
there in case we run out of anything else to talk about (which is
rare).

For more details on the location and write-ups of previous
sessions you can consult the associated wiki.
