We can’t using the service since 10 days ago, and we can’t access the url you mentioned http://mudfish.net/forums/10/topics/41549 if we don’t using SS. Now we don’t know the solution, if possible send us other link or write it down in the documentation page. Thanks.
Did you try to access https://mudfish.net/forums/10/topics/41549 URL too? I think HTTP is blocked for mudfish domain. 
Sorry for this issue.
