change suggestion ordering and fix template

The suggestions template had a few quirks that I fixed.

motivation... I've noticed that conference organizers sometimes ask for advice on how to submit requests, and was thinking about adding a helpful paragraph to go with the submit form. I started looking at the suggestion page and it had a few mistakes. I wanted to clear those up before proceeding.
