I recently posted a link to:
[url=http://www.youthhostel.ch/hosteldetails.html?&L=1&user_hostels_pi1[bez]=BAD&cHash=9e82d7c97a]Youth Hostel Basel[/url]
which, due to the square brackets embedded in the URL (..[bez]..), turned out:
=BAD&cHash=9e82d7c97a]Youth Hostel Basel
Clicking on the link got to the target, but very inelegantly. Is there a vBulletin way of escaping square brackets?
