Sure. You can hide the links so long as you hide them in this fashon:
[url = ON.TORIBASH.COM LINK] Words Here [/URL]
But
don't do something retarded like use ******* to further hide the URL so the only way to know what the link is, is to click it.
/knows he probably just gave a ton of people 'ideas'
//p.s. don't do it, if I see it i'm infracting you and editing your sig :O
