Web 2.0 Recommendations for intranet collaboration tool / wiki
I'm looking for suggestions on a decent hosted collaboration tool to manage internal projects, store files, manage to-do lists etc. I don't need heavy project management features, gantt charts and the like, just something pretty basic. Lots of file storage space would be a big plus.
I've looked at Jotspot, intranets.com and basecamp. Any others I should be looking at? Any recommendations from fanpoppers would be awesome.
Thanks in advance!
