Need a shortcut, too time consuming Options

[starlette]

Okay, so I don't know how many of you have been on my site, but I'm trying to make it a one stop shop basically with my music, my art, and then some web freebies like avatars and xanga codes. Okay so to the point, I have a little text area for my codes to go. Whens killing me is I have to go in and convert every single < and > to the alt version so it wont messup my other coding. What I'm trying to figure out is if there is a way to get dreamweaver to do that for me, or if theres a place online that I can plug it in and it will be converted, because it took me an hour to convert all of those little things and I don't have that kind of patience.
