If your question isn't answered - then it's just not answered. I would hesitate giving out check-marks to answers that don't help.
The acceptance rate isn't there to dunce you - it's more of a guide for answerers as a way to show the typical response rate from you (obviously 0% raises a concern) but it isn't necessarily a deterrent especially in a community this young.
So how do I get my questions answered?
Sometimes you just want answers - and the ones you have aren't cutting it. You can place a bounty on the question (offer a reward) to whomever can provide you an answer. This is great for questions that are more complicated / difficult to answer because the incentive will likely get someone to provide the answer
I figured the answer out on my own!
This happens all the time - and it's not a problem! Just post the correct answer to your question and accept that answer. In addition to providing the ability to ask/answer questions we're also building a database of questions and answers (Like a knowledgebase) so it's always good to have the correct answer to a question. Accepting an answer just because doesn't help us in that arena.
