If you've submitted a tab and are waiting for the admin to publish it, it will show up on your profile page under “Pending Tabs.” If you submitted a tab and aren't seeing that notice on you profile page, I doubt it's the system rejecting it, because unlike, say, ultimate-guitar.com, the system here doesn't auto-reject tabs based on their formatting.
That said, I'm no expert on this kind of thing. My first thought is usually “clear your browser cache and try again.”
Maybe on the requests page have a like button or something so tabs aren't getting requested multiple times and it can show if lots of people are wanting a certain song tabbed.
my only trouble is that no one gives time signatures or tempo. Not a big problem if you know a song but if it is something you don't know it is tough to tell if your playing it right.
I put in time sigs but not tempo. Because I almost always embed a video to play the song while reading the tab, I figure a tempo indicator isn't necessary. Besides, I'm too lazy to go back through over 800 tabs just to add a ♪= to them.
Because I am not really sure how to do it in proper timing. I am not good at that kind of stuff. I don’t even bother with metronomes when I play. I mean if people think I should just edit them then maybe I will but idk.
