On any strange machine (or on any strange browser as well - say you normally use Internet Explorer, and one day you use Netscape or Opera for a change) you just need to login, or you have to come in as GUESTweerover.

You just go to Quick Links, select "login" from the menu there and press Go. Then on the page that comes up, you indicate that you are a member, and it asks you your name - the name that appears at the top of your posts; and then it asks your password. And bingo, when you get back to the threads, it knows who you are, and your posts are headed "weerover".
