Okay i am not sure if this belongs here or not but I have a deeply frustrating problem.  My personal minecraft server that i use just to play by myself the multiplayer one is nice and works fine. Since i heard of mods and such things i was wondering how or where or who might have quality server mods for your own personal use.  I guess i am not saying this right. 

I have a multi-player Minecraft  server that i play alone and use for myself. I want to fly and to speed myself up [aka running, breaking, blocks etc]  and anything else that would be fun. I have a lot of things to build and want to play with my server save that i have made. Thanks for the help.
