Newbie (sort of) paladin help...

You really just have to do it more.
Learn to trust your healer and not use your CD's unless a bit hit is coming (and they're almost always going to give you enough warning).
Regarding being afraid of losing enmity, just keep a bar on the party list. There's a bar under everyone in your party that shows their current enmity on your targetted mob!

Thanks everyone I suppose I just have to try tanking more and don't be so afraid of messing up... and don't panic if I mess up anyway :P

Also when you're pulling trash remember to rotate your targets. It can be easy to lose aggro on a few when you're only focusing on one at a time. Use flash and Circle of Scorn wisely and rotate through all your targets on a regular basis. Doing this will show you any enemies that you're close to losing aggro on as well.
