I've been playing on this server since Feb 2014, on the previous MF2 Map, previous BnB map, and current MF2 map.
Frenetic (owner/admin) is quick to respond to any questions or suggestions, and the website is updated regularly. There are a core group of people that play, generally on MF2 that are really great.
There is a HAPPY sense of neighborhood, or community that you don't see going onto most servers. Also if you have questions, generally there is someone on that knows whats up, and is willing to help you. The hosted Mumble is great as well, no Server side lag for any of the packs or mumble.
On the few occasions that there have been issues, (read: tornadoes), Frenetic was updating us by mobile on the Green Acres Website. There is no down time, really, and truly. The world is saved very often and rollbacks are few and far between, and only due to pack instability. There are website competitions along with in game building competitions that are quite fun. New people join everyday and the adventure of finding people builds is great!
The custom made Mod 'Classes', by Frenetic, is really, really fun. At the beginning you may choose Haste, or fire resistance, later on you move on to Rogue - for invisibility, the choices people make and why, is intriguing, and I am looking forward to the changes ahead. One of the bonuses of playing on THIS server, is that if you make a good suggestion on the forums for this mod, Frenetic may use it! I was lucky enough to be around when she started the idea and feel like I was a part of it!
If you are looking for a MF2 server and you aren't super emo, please come try Green Acres out!
