There's a little bug I just found out.
The template timezonelist contains
PHP Code:
<img src="{images}/$lightbulb.gif" alt="">
The problem is when you are not logged in, the image is broken ($lightbulb is not defined).
So what I did is just changed it to
PHP Code:
<img src="{images}/clock.gif" alt="">
(When clock.gif is a little image I did with a world and a clock)
I'm using v2.0.3, so I'm not sure if this is also a problem on earlier versions.
EDIT: Just saw that this is mentioned before.

Sorry.
