A client wants their site revamping in WP. They have their main site and another related project site. This project site will start as a basic blog, but in the future they want to shift their project's social network side from their current Ning setup to BuddyPress.
Now, I know WP and WPMU are merging soon (3.0?). My problem is, my client wants the basic two sites up and running before I go on holiday in a few weeks. WPMU seems like it might be the way to go - even before they get BuddyPress going, they can run their 2 sites from one install.
However, while I know WP very well, I've never deployed WPMU before. I don't feel able to promise delivery before I go away - I don't know what the learning curve and have no feel for the scale of unforeseen WPMU issues.
Also - the time limit aside - is it worth going with WPMU now? Is WPMU for 2 sites, shortly before the WP/MU merger, overkill? Maybe it'd be simpler to have 2 WP installs for now and then when WP and WPMU merge, fold the project site into the main install. And then add BuddyPress.
I'd be very grateful for any pointers while I digest all the WPMU info on the web...
