How Does This Board Work?

I posted something the other day about an idea for a change to Bronze LP Mechanics. Then tried to look it up a few hours after. Couldn't find it... clicked Show More like 10 times. There were posts that were weeks and months old that showed BEFORE mine showed. I never even found it. I'm not asking how to find it. I know I can find my posts by clicking on my name. I just don't like that no one is able to see them. Here I am trying to strike up a board conversation about a topic I feel is important, and no one can even see it. How do Boards work? Why is my post gone and how will people even comment on it if they can't see it? I feel like I'm missing something. I'm pretty sure posts that get up-voted go first, but how can mine get up-voted if no one can even see it to up-vote it? That's not fair, and I can't just re-post it, 'cause I think that's against the rules. So what am I supposed to do? And what do the two up and down arrows by the title of my post do? I thought it up-voted or something, but clicking on either one put my post from "0" to "-2". Then I had to click them a few times to fix it back to 0. Someone please tell me what I'm doing wrong. How do I get my posts to be noticed? I'm really trying to talk about some important stuff. At least, it's important to me. Thank you all for your comments.

P.S. Would it be ironic if this post didn't get seen as well?
