Firstly apologies - my german is truly terrible, and babel fish only get me so far... If this is posted elsewhere, please ignore me!
I've got 2CSB installed (and slightly modified for formatting) and think it's really nice - but I wanted to add a hashtag in, which was surprisingly easy!
So I've added it in on my version as an option underneath the Twitter Username in the settings, which then gets appended to the text.
If anyone's interested, I can easily send the changes - the key thing is to use %23 instead of # in the url creation.
