I recently asked this question and got some good answers, in one of the comments DVK mentions that reputation can be recalculated, and Gilles then provides a link to do just that.
When using Gilles’ link I do get to a page where I can select a recall button. I cannot, however, find a link to this link off the main site. (It might well be there, but I couldn't find on the reputation page where I assumed it would be.
So is this option freely available to everyone? If so, where is the link?
