Math, considering about a dozen new threads have been made, and I can see this one living longer than a lot of the new ones, just let this one stay open. It is border line worthy of its own thread but so are all the new ones.
We should clean up some old and unused threads sometime to make way for ones that will be used. So yeah. Can ya let this one stay open, so long as it doesn't turn into a repeat of the last/closed one? Sanku
