I would like to install a groupware script, but have no idea which one is the best...

I've tried PHProjekt and it's OK, but I don't really like the look and feel of it.

What level of functionality am I looking for?

- an email client, preferably with the possibility to set up multiple existing IMAP accounts

- an address book function

- some sort of file manager, to be able to upload/download files easily

- calendar

- some kind of project management (doesn't have to be a huge thing)

- forum/chat would be nice

- some system where I am able to write small notes/memos


But most of all, I want it to be 100% web based

Currently I'm looking into PHPgroupware and more.groupware. Does anyone have any experience with either of these?

thanks,
