Seeking Office Management Software

Hi there,

I've been this online office management system hyperoffice.com for a while now & I never liked the program b/c of all the bugs, it wasn't designed properly (user interface) & tech support always blames us (not just me, even my VA & techie) for their issues, plus they don't return e-mails when one complains or asks for a credit for all the problems.

It even went down last night & no apology or anything when I wrote to them.

I'm looking for an Open Source program that I can use instead & put on my server & have a programmer tweak if necessary. I only deal with MySQL/PHP

Any suggestions?

Here are the features I need...

tasks
calender
groups & permissions
file documents
links/bookmarks

etc.

Thanks & have a great day!
