Hi so, maybe it's just me but a few times I noticed a situation where an user will half answer my question, and another user will do another half. So both answers would be correct and should deserve credit, especially if one is taken from the other. I think this is important when it comes to points, too.
I've also had this happen when answering "how to get ___" questions, where one answerer would provide one way and I'd provide another way, both are technically correct and could be considered best answers.
My idea for this to prevent abuse would have to have a staff review the answers before allowing there to be more than one BA, up to any of their deemed standards if this becomes a thing. I'm thinking maybe a checkbox or a button similar to the "flag" one that says "request second BA" and a small description of why for the staff to review, and then having the two answers combined into one answer, giving credit and Best Answer points to both users (or splitting between).
EDIT: Sorry if there's typos or if this is incoherient-- it's nearly 1 am and I worked all day and I feel like a zombie. Tell me and I'll fix asap
