Over the last day, I’ve been working on the website a bit.
The first change is the addition of the “Distribution” tab. This allows easily sending a copy of the scanner to all the people you rated positively. To avoid annoying people, only people who don’t have a scanner and have never been offered one before appear in the list. Also, the feature is limited to 10 deliveries per hour. However it also means that you can safely click the button every hour until it’s delivered to everybody, and nobody will get offered a scanner twice.
The other addition is that now every avatar name links to a page where all the ratings for an avatar can be changed. This, combined with the history page means that if you accidentally changed all of somebody’s ratings to “None” (and that way removed them from the ratings list) you can now just click their name in the ratings history page, and rate again as needed.
