Should you remind people to upvote your questions? Is this helpful/necessary? Would this be considered rude or inappropriate? Thank you for your input.
No. You should not ask people to vote your posts or accept your answers. That is inappropriate.
I know how it feels like when you're just starting, and it's hard to get more points. But that's why you need to work hard, post good questions and good answers, and you'll get there in time.
