What gets up my nose (and not just on here) is the poster who asks for info/help about some damned thing or other, gets one or more replies, then nothing from the OP - no thanks, comments, reports of success, just nothing. Manners seem to be a thing of the past for some people these days!
OK, so I'm a grumpy old git, I'm an OAP, I'm entitled to be one!!
This point has been raised on a number of forums and is a valid point. Unfortunately, the end result can be that those who could assist often don't bother after a while.
