Hi queen_mab -
Once you log in to your Sellathon account, you will notice this at the top of your home page:
"yourusername", member since xx/xx/20xx
License: Trial (Unlimited auctions)
Expires: 20xx-xx-xx xx:xxam/pm
Archives: 7 Days past expiration
Before your trial time expires, you can choose to continue using Sellathon and change your status to a paying account. Just click on the "Your Preferences" link at the top of the page. Or you can just use it for the month, download the data and let you account expire naturally. It depends on how much value you place on the information Sellathon provides you.
If you choose to let your Sellathon account expire, you can still use the counter at the bottom of your listing to track views. You just will no longer have access to all the other information.
Hope that helps clear up a few of your questions

P.S. The "unlimited" part refers to being able to track information on unlimited auctions for the trial month.
