I searched, but did not find something about it.
I just created a contribution. First, it had a “+” in the title. I changed that later, but the url stays the same (which is good).
But no matter what I try, I can’t link to it from inside the forum, I always end up with a URL that returns me a “page not found”.
Note that this DOES work inside the “Preview” area when writing a post. Seems like some postprocessor runs only on hitting Save and mangles the links. When editing again, all links look wrong, and I also can’t make them work.
Finally, I shortened the URL to make it work. http://goo.gl/pV33V
