Honestly, if this is supposed to be the April Fools prank, it was mis-timed. You should have tracking information for where most of your user-base is, right? That is probably Europe or the US, with a strong presence in Australia as well, given that this is an English Language forum. So you should have gone for something like noon in Europe as your posting time. As it is, you posted at like 10 PM US Eastern, on the last day of March. It is only twenty-three minutes into April Fools Day as I post this.
As to upgrading, I am not sure why people are complaining about Xenforo 2. It isn't that bad, at least on PC. Maybe it isn't good on mobile? I don't know, I don't use a mobile device for internets. And frankly, given that Xenforo 1 is no longer supported and getting to be more of a security risk each month we are still on it? We need something else, probably Xenforo 2 for easy of upgrading.
