I asked this question. The question itself is probably not very interesting and not very useful for almost anybody else. I really needed to get some feedback. I was surprised that two guys almost immediately dealt with the problem for me and provided two working solutions which shown me another way to achieve it (despite the fact that I didn't used those solution for other reasons).
Now the point - I think the question was complex and it took some time to understand it and provide working solution (which is in big contrast to many highly upvoted answers) but I can't give those guys no more then one upvote and mark one answer. I would like to be able to reward some reputation bonus (transfer my reputation) similar to bounty system (I guess, I can't start a bounty once I accepted the answer) just to show that I very appreciate their involvement.
I know there is some general feeling that if you want to award somebody with more reputation, you can go and upvote his other answers. I'm mostly against this approach because I only upvote answers which I think are good and correct = I must fully understand the question and the answer. It is not always possible especially if I never used related technologies.
I'm sorry. I din't know that I can start bounty on answered questions. It partially solves the problem but I still don't like the idea that I must wait 24 hours to award the bounty in this scenario.
