Students intending to support our solar site, after browsing to the Share It link (https://area51.stackexchange.com/proposals/119468/solar-energy-science-and-economy?referrer=KBKRhv89SyAy_-rWx8ONsg2) found they had to confirm an email to create an SE account, which makes sense.
Then they found they had to confirm another email to Follow It for the solar site, which WOULD have made sense if they hadn't already confirm that their email is real and properly associates with their account previously.
If this is a bug, then I've placed the right tag in this Q. If not, then we should remove it. If it is intended behavior I suggest reconsidering that intention.
Two email confirmations give people the impression that SE is too complicated and will reduce engagement statistics. For individual proposals, the double confirmation makes it unnecessarily difficult to begin following a proposal in a critical stage of development.
I can't think of a valid security reason why two confirmations should be necessary, especially when only 60 seconds apart. It's not like a man in the middle attack or some other security is realistic in that short a window of time or that following is such a profitable thing that anyone would hack it anyway.
