From now on, if you DO NOT select a Most Helpful opinion on your question, the system will choose one based on engagement for you after 15 days. Neither the QA nor the person awarded MH will get the usual Xper points for MH. It's chosen based on engagement: votes, comments, length, time, xper level, gender, among other criteria. As long as you're giving helpful opinions, we'll find them!
We encourage everyone to remember to select a MH opinion within 15 days so that YOU and the user who shared can get the Xper points for selecting and being chosen!
I just figured that what happened wasn't a glitch. It's actually done intentionally by the admins. Go see your old questions (asked before the update) and you'll find that ALL your questions have a MOST Helpful Opinion selected for you by the admins. I had some that I hadn't selected MH for, but now it does. Hahaha!
I don't know if the admins employed a random selection process or if they selected the answer with the most up votes, comments, number of words, etc...
It would be AWESOME if we received more Xper points corresponding to the extra Most Helpful Opinions. :D
