Korijs, there is a trick. Use this URL template:
where you replace THREADID with the thread ID and MESSAGEID with the post ID.
For example, if we have 738 as Thread ID and 14388 as Entry ID - http://take.ms/Nd1Xd - the URL will look like: http://yoursite.ucoz.ex/forum/1-738-14388-16-1
hey i'm joe, please don't call me on my real name because you're gonna misspell or mispronounce it and it drives me nuts
