1. Equestria 1- Our earliest and by far worst attempt at making Equestria, this was back when we were a hybrid survival creative server. While our initial attempt at building Equestria didn't go so well we managed to form a solid community out of this early attempt.
2. The first admins - While this is not meant as a sign of disrespect to my current fellow admins (you guys are awesome!) some of the early Brohoof admins were just amazing. I have many fond memories of time spent with Orsh, Ned_Turbo, Lost_Luna, and others. My experiences with these people are some of the first things that pop into my mind when I think about the server.
3. The Pony Mover - Probably the most memorable thing from Equestria 2, the Pony Mover was an awesome automated tour of Equestria 2 and videos of it greatly helped in drawing in large amounts of people. Sadly this video seems to be the only one left of it

4. Equestria 3 - This was perhaps our greatest breakthrough. Through extensively premaking our map of Equestria we managed to create one of the first highly show accurate maps of Equestria. Another big thing I remember about Equestria 3 was all the complaining people did before they saw the new map, it was very funny to see the moaning to turn into applause when people saw how much better everything looked.

Messing Around With Admin Powers -
Random Lighting, Rocketing People, Turning into an Invisible Pranking Ghost, Scootanukes, Spawning tons of Ghasts, Scootanukes, Disguising as Random Mobs, Impersonating Ponies, these are all things I have a lot of fun doing during my time as an Admin. I mean uhhhh I totally never did anything like that nope not at all.

6. The Brohoof Training Video - It was a magical moment to see this thing come into existence, it's been one of the most useful things for introducing new people to the server we've ever created and I felt proud to be a part of a server with such a high degree of quality and professionalism after watching it.
