I think Best Answer should only be at the discretion of the OP.
Not interested in emojis - don’t know what each one is and have no desire to. Leave that for those who are on social media. Not me!
I do not consider AB as social media - to me its an open forum.
The ability to edit a post would be good - especially if you’ve made a typo, or hit the Answer button too soon.
Automatic filtering of spam posts for gummies, cbt, keto etc. - anything with those terms should not publish automatically, instead be pending until approved by a moderator. Especially at weekends!
Fix Youtube links - mine never seem to embed.
Image upload would be nice, but not necessary - image hosting sites are available, but admittedly some of the surrounding images on the resultant hosting page may not be appropriate!
