BizDevGuy’s favorite project management and collaboation site
Most BizDevGuy clients get introduced to BackPackIt, a very inexpensive collaboration utility that is free to our clients (unless they want to create their own pages.). As a central repository for to do lists, notes, files, graphics and a number of other collaboration tools, it does a lot of the heavy lifting while remaining simple to use. BackPackIt is a product of 37Signals, the makers of BaseCamp and other very inexpensive collaboration tools.
The interface is quite intuitive but not quite WYSIWYG, but for about $5/month you get a lot of functionality that continues to expand as the folks at 37signals keep getting smarter.
