@Lord_Bowserinator(View Post) What is your username? When you get online try just asking for help, it will be relayed to IRC and I might see it.
Anyway, hopefully you found the redesigned nether hub. I suggest heading north from there, pretty soon there is a sign which says "< End portal", go that way.
We used to use the southeast one, but I think the north one is a bit closer.
@2312352(View Post) Well if you have the email you used to register it still, you should be able to get it back. Mojang support might be able to help you if not.
@Lord_Bowserinator(View Post) First you have to make sure the farm is off (it won't let you leave unless it is off, because the farm breaks when the chunks are loaded/unloaded while it is on)
Then go to the very very top, there is a minecart ladder. You have to jump up to reach it, then hold right click until you are at the top.
