html linking in posts?

I recently noticed when trying to use the correct syntax to link to a person or thread without displaying the link itself, it comes up with all the coding shown. I suck at explaining, so here. <a href="http://maiotaku.com/p/jikokun">Should link to me</a> See what I mean? Anyway, is there a way to allow the html syntax to work if inputted? I know it worked before, and I'm guessing it was changed when people no longer had to use html to post pictures and just post the link itself. Anyway.. just wondering, thanks.
