Why can't I post?

[jens]

Usually when this happens it's because there is a strange symbol in what you are trying to post. So if you are for example copying a text from a word document and in that copied text there is a strange symbol then you'll be refused to post.

As you can post here and reply in this thread it seems to be working fine, and the problem is only related to that thing you want to post in the quick questions. right?
