Nabble Forum Registration Problem4564

When I try to register for the LibreOffice Nabble forum, the captcha does not work. It shows letters and numbers with spaces between the characters, however no matter how the characters are entered, either with spaces or without spaces, it says the entry is invalid. Below is an example of one it said was wrong.

Who do I contact about this problem?
