Thanks for the information Cena & Lane. =)
I really like Alex King’s tasks software but it lacks the feature of file upload & management, which is practically the most important thing I need.
Using a weblog for project management would be good. I thought of the categories thing, but felt that would be too ‘manual’. Also, I want something I can login to & have the important things presented to me on the front page.
I did poke around on OpenSourceCMS, lane, as well as TikiWiki, which has waaay too many features than what I need. Currently I’m considering Moregroupware or something along that line. Something simpler would be nice.
