Ok, I found the editor thing for freewebs... I think. lol. Well, I don't exactly know how to put backgrounds and stuff. Can somebody help?

If you tell us what you don't understand in the FAQ entry Darin pointed you to we'll try to explain it to you.

I would tell you in much the same way as it's said in the FAQ, so that wouldn't help. It's easier if you say what goes wrong.

Ok, well, my problem is that I don't even know where to put anything and I don't even know how to make html stuff....

Well, then you have no other choice than to follow Darin's other suggestion and work your way through a HTML tutorial or two.

^Alright, thanks!
