The easiest-to-set-up wiki I’ve ever found. (PB = set it up “as easily as a peanut butter sandwich”). And it’s true. I’m using it for my to-do list and to collaborate on a document with my friends. Not too fancy and not bloatware. It’s just simple, free, and it works!
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
