Been there, seen that and I DO NOT like it, for it also prevents successive posts. In forum, debates I usually like to set up all the posts I want to respond to and write my responses and then post them one after another so that they stay together, and this tactic prevents that, as well as just posting multiple quick successive responses, thus wasting more time. Other posters on forums that prevent this have also complained.
You must have a slow connection if you keep trying to post the same message.
What forum do you see as the best example of what one should be?
You can set the time to 10 seconds or even 5 and the only thing it would stop is unintentional double posts. I have gigabyte fiber and I’m not the only person who double posted in this thread.
