Sorry about that!!
I got the same message too!
Well here's the way it's supposed to work:
At 3pm everyday the system checks to see if there's been any activity to the reports on your "watchlist" or by the people you've followed, if so it sends out an e-mail to you.
When you contribute to a report it automatically adds it to your "watchlist" you can remove it from your watchlist by going to the report, and at the botton right-hand corner click on the button that says "remove from watchlist".
You can also see every report on your watchlist by going to www.productwiki.com//watchlist and manage the list from there.
As for minal081... I'll have to check if that was supposed to happen based on the design, or if there's a bug in the system.
