i am interested in having a small mohaa server. my internet isn't the best so i figured a 4 or 5 player server. how do i go about getting the usual maps and adding a few modded? or how do i even mod a map? any suggestions will be appreciated.

I'm not sure I understand the question, but a good start would be visiting TMM World. There's alot of great information that will probably answer most of your questions.
