It as been a while since I haven't been on the community forum. And I can't find the "make best answer" button.
I also looked up on the forum and some people were saying to click on the green button, but I can't find it.
This is from an "old" snapshot (in French) when the forum launched but it should not have changed much. The buttons are located underneath each answer.
So the rules might have changed recently for the two special forum categories as I observed best answers were sometimes attributed and sometimes not (with points gained or not):
TBH I'm a bit confused as I think they changed along the way and also because I believe Whizz kept that "choosing best answer" capacity to themselves on the Data Gifting one. 🤷♀️
But the other categories (Welcome, Internet, Phone, ...) offers that capacity to people posting questions.
Yeah, it seems that way. In some categories you can‘t choose best answer. I never realized that until Idefizz mentioned it. I now had a look and it seems he is right.
But, it's not there for one particular question I asked.
