Levels are based on xp which is tied to your submissions. It's impossible for me to remove levels without removing submissions, and you haven't had any submissions removed in months.
Everyone will (or eventually will) appear to be level 1 temporarily as the new forums are put in place. Once they've finished being updated, everything will go back to normal and it'll show the correct level number for you again.
On the right side of your profile under the big banner at the top of your page should be a button labeled something like "+ Widget". One of the widgets is a wall post thing.
I hate to broadcast my ignorance like this, but what is this? Is this a "wall post?" I like the idea of being able to post a teaser of upcoming projects, but I don't know how to do this... Thanks (if you end up responding)
