The biggest thing to understand with FM is do NOT take anything personally. If you are getting pushed, dont worry since a lot of the time people push for information, not always from you either. a lot of the times i will vote and push at people just to see how others (sometimes specifically 1 person) reacts.
If you are town: try to think from the mentality of a scum. what would u do if u were trying to hide from town and mislynch towns. what things stick out as seeming like someone has "more information". example of that would be someone KNOWING someone is town. seeming too confident in that it is a mislynch, then trying to play the "told u so" card the next day to gain town credit.
If you are scum: try to fake scumhunting. or just look for neutrals and toss neutral/mafia when trying to find lynches. try to help town, but not reveal enough to help them too much. you want to try to balance how much info u give.
if ur neutral, just have fun, explore the game and try to target a mafia
practice scumhunting, try to genuinly FIND the scums. it will be like a good practice run for u.
Its a slow process of analyzing info and progressing in how you view the other people. but once again, don't take anything personally. even if u get voted up or mislynched or accidently scumslip or something and out urself. tensions run high as well as frustration (real frustration is a good town tell btw, fake emotions are a good scumhunting thing to look for), so dont feel horrible if someone starts saying some mean stuff, it's somewhat common in FM and non of it is because of who we are personally, it just gets very, very frusrtating trying to figure things out - especially when its like D2+ and people are still trolling =P
