One of the more exciting projects I'm working on right now is a semi-major website for the as-yet-to-be-announced "Client B." ("Client A" is the as-yet-announced DVD project client.)
(A note about as-yet-to-be-announced clients: Sometimes you want to announce the new gig right off, and sometimes you want to line up your ducks first -- and we like to have our ducks all lined up in pretty formations before the fanfare starts.)
Anyway....this will be an interesting site because we're building it in Drupal but, in the end, will be approaching something similar to what a CivicSpace installation might have yielded. (I won't go into the why's of not just using CivicSpace except to say that this was the client's preference.)
A big part of this project will be the incorporation of CiviCRM into the site. The site's membership is expected to jump up into the several hundreds in the early going, and having robust membership directory management features will be key.
