forum standard which should mention what is the expected wait time to get a response.
These forums are staffed entirely by volunteers -- and the "wait time" depends on many unpredictable variables - i.e. time of day/night, how busy the forums are, how many volunteers are around, what your issue is, etc.
And when you bump, it actually removes you from the "unanswered" list, so your wait may then be much longer.
