UBB Code will break the line once it reaches 140 charecters in length, causing some troubles.
Generally, if the URL is that long, you should either 1. Post directions to it, or 2. Learn HTML and post a "Click here" message.
But, and this is a big but, don't do HMTL if you aren't absolutely, positively, 120% sure it's right.
