One good way I would say, is to try and give yourself a notable identity, that everyone can remember you by
For example
Noipoi
's known as the friendly guy who loves to draw, and enjoys Pokemon.
Zinith
's known as the guy who really really likes Yoshi. And I'm the known as the guy who really likes Corrin, and has an unhealthy obsession with Rhythm Heaven and wanting Steve in Smash
What are you passionate about? Don't be afraid to let your true passions and personality show. That'll help give your posts some true personality, and people will be more likely to latch on to ya
Oh, and also be nice and well behaved, (You doing great on that, btw)
