So, basically you're looking for a Base10 to Base26 conversion function?

i strongly object the fact that users have, during the last couple of months, started to abuse EE's "request removal"-option instead of awarding points to the people responding to their questions.

The page I linked to gives not only one, but a multitude of distinct possibilities of solving the problem. All the author needed to do is choose the one that suits him best.
