If no one is in the other sections, post there, anyway. I think most of us just look for new posts and all of them come up.
The little rings are for keeping track of stitches on your needle, rather than counting rows. There are little row counters available that you slip on your needle and turn each time you finish a row, but you probably don't have one lying around.
You can count your rows with a hatch mark on a piece of paper, or when I have a specific number of rows to do, I write those numbers on a piece of paper and cross them out as I complete them.
Or you can just count the number of v's up from the bottom and that will tell you how many rows you've knit. If your knitting has a stitch pattern, though, keeping track is the most sure way.
