Welcome to Geo-counter House
Keeping.Registration lets you do a few more things, like auto-resets of counters, and retrieve extra stats. It will also help choose a "good"/unique name for your counter(s).
If you are NOT a current Geo-counter user, and you're NOT from the UofA, YOU CAN'T GET A NEW COUNTER, so you may not want to register, given that it's useless to you! Go back and read the TOP of http://www.ualberta.ca/GEO/Counter.html
