OK, so the concept (which is not being grasped) is this:
You ask a question
Someone posts an answer
The good answers get rated up
The bad answers get rated down
You can have more than one answer, these will rise to the top
The best answer (or the answer that was implemented), can be selected by the OP or by staff.
Why its not working for you?
Q&A is not a conversation topic, so if you are going to use it as such, you will be forced to select "date order" sort each time to allow you to follow in that manner.
If you are quoted, your alert will take you to that post
If you are tagged, your alert will take yo to that post
If you are using the search correctly, it will take you to the next unread
You cant ask another question further along - you need a new topic
Why do it?
If you have a question, when others come along later they can quickly find an answer or suitable answers, rather than sifting through 20 pages of chatter.
Questions that are asked regularly, can be rated up, so that they appear at the top of the list. This helps newcomers in answering the same questions that get asked over and over.
