In the old forum, you could post in a thread, then make another post in the same thread later, and if the two were consecutive it would automatically merge them. This doesn't seem to be implemented in this forum, and it's something a lot of people would probably like to have back.
Ah! We do have this option but I disabled it while an issue was fixed, however checking the documentation I can see that the issue was fixed and we are now able to use this feature. I've enabled it and set it so that posts that are 5 minutes apart are automatically merged: do you have any specific time frame you think would be ideal?
Make two consecutive replies auto-combine, like the old forum
