Making a textboard

Did you ever make one? Which frameworks did (or would) you use? Did you program any unique features? Do you host it?

A C based system would need to process HTTP requests, do url-encoding, translate/filter HTML entities (&) and all the stuff web technologies have builtin. Not to mention heavy-duty string processing. Don't use C... Even if most skilled with it. Will probably use a database (though flat-files aren't unheard of).

The organization in multiple files and folders is typical.
