Online app for project management with a group?

Hi all, I’m new here, but have been reading 43f for a long while and know that y’all will have some good ideas…

I’m starting a new job where it’ll be necessary to track large projects that have lots of players, lots of tasks, milestones, comments, etc. The usual mishigas.

What I’d love to use is some sort of web-enable app that allows everyone internal to see the projects at a high-level, then dig down to see (and depending on their role, edit) administrative detail and related comments/conversations. With a good tagging/search capability. So, very bloggy or wiki-like, but well-organized.

A good wiki might do the job, but I haven’t seen one yet that looks easy and fun enough to use.

I know this sounds hopelessly vague, and probably naive, but I’d love any advice/suggestions – thank you!

Can't say yet for 1.0

I just now signed up for the hosted 1.0 trial, and it’s got several features beyond what 0.7 did (tickets, more polish, quicker adding of new items in some situations, etc.). The one thing that was most irritating about 0.7.1 was the inability for a regular user to delete a file they uploaded. It was good about letting them upload newer revisions, but outright deletion took administrator action.

I’d say sign up several of your team members to the hosted trial and see if you can mock up a project to your satisfaction.
