I am looking to set up an intranet software package at work that would
fit the needs of about 30 people.  Something along the lines of Manila
Userland.  It needs to have e-mail, file sharing, web editing
capabilities, blog options, forums, public folders, file transfer...is
there a simple solution to this need?

If you're interested, you can try quite a few Open Source groupwares
(scroll down a bit) and test their functionality.

and phpnuke and phpgroupware are very capable of handling the options
you request. And the price is right, too.
