What is the best free Intranet PHP script (groupware) available? I don't need it to be perfect, just to have all the basics: project management, calendar of event, address book, discussion board, etc.
I searched HotScripts for that matter, but there are only just a couple that I like. I thought maybe you'd know of some better scripts.
Actually, I'll be ready to pay for it up a small fee.
User-friendliness is the #1 priority.
Stability is #2 (I won't have time dealing with fixes).
I'd greatly appreciate any advice or suggestion.
