I have registered to this forum a year ago and the last time i was there, the threads don't work well. I also can't respond to threads. Its a lot better i guess if they just use another script like vB or phpbb or mybb than xenforo because their server seems not working well with it.
This forum has been updated a lot since 1 year ago.
There should be no issues what so ever, also were using the best software on the market for forums.
