From a customer point of view, I wouldn't use this much, even though I can't code HTML I wouldn't want to try use it.
I know if I did have any problems, the host would be the first person I would think about contacting, even though many hosts don't expect customers to ask for advice on scripts they provide, customers do need help on using something they have been given.
It's like the army giving it's troops a tank and telling them to fight a battle, they will to know how to use the tank to make any use of it, otherwise it's easier to just leave the tank alone.
Sorry for the bad....connection (Can't think of the word!) but I was watch F911 and that was somethign that just came to my head.
