Just a friendly reminder...
Another little effort users can take is to add 'Message Tags' to each reply or post, which helps in listing the post in future when searching for existing solutions.
They make the instant result search faster because the backend doesn't have to search all contents of all posts. This is also a little community building activity even if you are not really posting answers or solutions.
When I get the email "Did you get the answer you needed" and the answer is no, what is one supposed to do? That's when I call GTAC or give up and move on to something else.
