Is there a way to transfer reputation from, say, stats stackexchange to math stackexchange? Is this planned?
Many here are experts in one field (and can earn a lot reputation there), while they learn in another (and could use reputation to offer bounties there etc.). Maybe that's the economist in me talking, but since reputation is already treated like a currency, we might as well reduce inter-platform restrictions and let reputation go where it is needed most.
The only way I know of to transfer reputation (sort of) is when you have enough reputation on one platform, then you get +100 anywhere else. But I think that's as far as it goes.
