I posted a question early this morning. So far it has very few views and no answers or comments. It's a complicated topic and I want to add a bounty to attract more attention and hopefully get an answer faster, but the system won't let me.
The "start a bounty" link is available for my older questions, but not this new one. Why is that? Is there a waiting period after a new question is posted, before a bounty can be added? If yes, what is the waiting period and is it listed anywhere on the site?
And why have a waiting period at all? Suppose somebody wants to provide an incentive to get an answer quickly, rather than waiting around for several days? Why not let them offer the bounty immediately?
