WordPress MU

Hello Wordpress MU family,

I've trusted you all for a few years now with my questions regarding community design and integration. I now am at a crossroads with one of my sites.

The site in question is my mushing site. The problem: we've become to "spread out" (e.g. we use phpBB, drupal, classifieds software, wordpress mu, etc...) What would you say I follow, as a path, in trying to choose the best CMS and management techniques for my site?

Would you suggest I use a simple CMS or static pages for my articles, news, etc...And leave community, etc...to Wordpress mu/buddypress? Do I use Wordpress as my main CMS - or will I find limitations.

I'm comfortable using Wordpress, Drupal, etc, etc...BUT - I want to choose the best solution in helping my users to feel comfortable with an easy to travel website.

Thoughts would be appreciated.

Website I admire - for design, community integration, etc...

See, I think using both MU & Drupal is redundant. I'd pick the one I was most comfortable with (in this case, MU).

Using the main blog from MU as a simple CMS is totally do-able thru some theme changes.

As long as everything is integrated in terms of looks & navigation, it should still be easy for users.
