How to make your font invisible on AIM profile.?

I know this can be done. I've seen it before. The only problem is that I can't seem to do it. I've tried to change the font color and background color so that it'd be the same; but if I do that, the font color always changes so you end up seeing it. Please tell me how this is done?? I want it for my profile. And please don't suggest changing the font color to match the background as I have already attempted that and it failed.How to make your font invisible on AIM profile.?
