Iím having a problem with a site I am building and right now it looks like using iframes are the solution.

Having never used them before I was just wondering if there are any reasons I might want to avoid them? Just curious, I donít want to launch the site and find out three weeks from now about some negative issue iframes cause.

Anything I should look out for? I know a lot of mobile devices donít support iframes but thatís about it.
