the Modding System is as same as the Teaching System, but here, you need three separate things.
(NOTE: the Modding System talks about Abilities that someone wants to learn when they achieved their new Rank-up)
1.) the Downloader
2.) the Uploader
3.) the Program (Ability)
Basically, the Downloader will ask the Uploader if he/she can have his/her Program (in-character, via pm, via chatbox). If the U-loader says yes, make a topic or a post about it. Then roleplay the downloading session. After that, the D-loader will automatically learn the Ability. If the D-loader wants the Ability to be added to his/her Character Info, the D-loader must ask an Admin or a Mod to ask an Admin to do so.
