I'm now Usul instead of _Tsk_ on irc.mozilla.org. It's one character shorter. It was available, and I'm a fan so I took it. I did that while watching the Dunes series on TV. I now have a nick that people can pronounce, I sure nobody will pronounce it the same way :-)
I'm a big fan of the book too :-) I just changed nick while watching TV - but I'm found of the book over the series (as it's the case most of the times).
...And yet you're named neither Paul nor Atreides. (No, I didn't watch the series, but I read the books, starting maybe some 25 years ago.)
Well, the Fremen language is supposed to sound Arabic-like, isn't it? Then that name should sound something like أُوسُول or [usu:l], I suppose. (And I'm too lazy to check in my Arabic dictionary the exact spelling for "the base of the pillar" ;-) ).
