I don't know if it's just me, but it looks like there is a minor problem:
If I go to a page with a list of threads, e.g. this one:
http://forum.linda-chung.net/forumdisplay.php?fid=14
At the top of the page under the banner, rather than the usual "退出" "短消息" etc., I'm getting weird characters like "嚙篁嚙碼" "嚙線嚙踝蕭" etc. In fact these characters appear in places elsewhere on the same page. My character encoding is set to Big5.
Also, this issue does not happen on the main forum page, nor on any actual page with posts within a thread (like the one you're reading now).
Just thought I'd report this issue so that you can have a look at it if you have time.
Cheers!
