It would be great if you actually showed people how to FIX the problems they have with HTML. Like for example: "There is no attribute *whatever*"... If it's something commonly used like "topmargin," could you please tell us what we can put instead of that to get the same effect? Thanks.
For example, I was trying to help this site: validate its stuff. But I can't help them because I don't know a replacement for a lot of the stuff that's "not real."
