I have a question for which I want to start a bounty. The "start a bounty" is missing.

I checked this before asking here and I learnt that, per user account only one active bounty is allowed. Is only one active bounty allowed per user, all his stackexchange accounts puttogether? However, that - for the moment - is academic interest only, because I checked I have no active bounties on any of my stack exchange accounts.

I read through the page on all about bounties, and found that as regards the age of the question, the lower limit is 2 days which is clear in fact at the moment one posts his question.

But the question in concern was asked in 2012. So is there a tacit upper limit on the age of the question for starting a bounty??
