The biggest thing if you're town is just look for people's motivations. Read what they're saying and ask yourself is this person really trying to find mafia (if you see us call them scum it's the same thing) or are they just trying to give off the appearance that they are. When you think someone is scum, vote them, see how they react, and continue to think critically. Keep an open mind.
Another thing you can do, and I don't think I'd recommend this once you get the hang of things on your own, is pick someone you think is town and seems to really know what they are doing, and just follow their lead. But if you do that, keep in mind that the person you are following could easily be scum manipulating you. So be careful with that.
Ask specific questions. If something stands out to you or confuses you, don't be afraid to ask. Your alignment (meaning which side you are on) will become more clear as you post more which can only help if you are town. So post often, openly, and genuinely. You should have nothing to be afraid of doing so unless you are mafia.
Try to develop an opinion on everyone as far as whether they are town or scum and make that opinion clear and make your reasons clear. Be willing to admit you are wrong at times and it's ok if your read changes as long as it's for a good reason.
If you're mafia, sorry but I'm not helping you
Have you read the game in full? If not, please do and get back to me. If so, what is your read on temp? What about anyone else? Does anyone stand out to you more than anyone else?
