Here we have a summary of Composr's major features: as you'll see, you have many to pick from! You don't need to be a Rocket Surgeon to see why you should use Composr.

Remember that almost every feature in Composr is optional. We hate web software that forces too much on us (and the visitors), so we ensure Composr scales back and customises very well.
