Dora the Explorer?

I've been less than active lately on SlothMud, but do keep up with the progress made. Among the game play changes (some of which were less than well received) was the addition of the exploration tracking. Roughly every room visited is tracked on an individual player basis, in order to calculate the percentage of the world visited.

It is a relatively superfluous statistic to track but it is a badge that can people can compete for. I don't think we have implemented any in game effects based on the level of exploration. However, I was surprised to see that Splork (I think) made an explorer leader board available on the website.

I know there were some bumps when it was originally coded, but it seems as if it is pretty good now. I'd be interested to see how the actual statistic is tracked as I don't think it was trivial coding to:

• efficiently track each room number that every player visits
• uniquely identify every room which is able to be reached by mortals

At any rate, I'm waiting for the character Dora to be at the top of that list.
