I've got a couple sites going with MT now and am beginning to feel comfortable with it.

On the other hand, I have another site for which I bought pMachine. I simply cannot get used to it.

Seeing the MT site here helps me see that some of the functionality I was wanting from pMachine might be available by combining MT with other Open Source software.

So far I've found a way to do web-based e-mail (Squirrelmail), a forum (same software used for this forum) and, of course, blog (MT, yay!), but there's still one more thing I need: a web-based calendar.

Does anyone have a recommendation for one that could easily incorporate into an MT-based site that will allow for members of the site to add or edit events? Even better is if it's possible to have different levels of access for officers of a group versus regular members.

I'd like to just dump pMachine and stick with MT, squirrelmail, Invision and whatever I can find for calendaring.

Thanks!

P.S. If someone is already doing this, I would love to see an example of how smoothly the calendar fits into your MT-managed site.
