[Suggestion] Allow Q&A challenge to be disabled and allow wildcard answers

The Q&A challenge has been a great help in stopping spam on our forum, it seems.

There are two additions that would be very helpful:

1. Allow a question to be disabled so that we can try a new one, but without fully deleting the old question and all of its possible answers. An option to disable would be great.
2. Allow wildcards in answers, e.g. We wanted to ask what version our software is up to, but don't want to add every minor version manually, so were planning on accepting "4.*" and "5.*" as answers, but that's not possible currently.

Thanks for listening and considering these suggestions :)
