While I am undecided whether or not to add me to the map, I have one stupid question: How? (Seems I'm the only one not finding that out? :P)
I can not find any "add marker" or such? The only thing resembling, is the link "new" at the upper right, by the "My profile" link if logged in to a google account. But that only brings up a preferences window.
And while I'm at it, how do you add yourself to a generic area? You just put a marker in the middle of a forest or something? 
Btw, while going back and forth between the map and writing this, I noticed one can drag the little guy above the zoom-in plus sign, but how do you get him stuck on the map? All that happens, is that some image for an area pops up, and I'm still pretty clueless..
