Here is a typical error message I get when I try to double post on most of the sites I visit that allow comments (note that the time between posts can be set by the administrator and varies from site to site):
If sites that don't ask for money at all or at most have a donate button at the top of the intro page can manage it then the feature can't be very expensive to implement.
Yikes. I guess we are all different, cause I’m glad it doesn’t do that. To each his own.
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?
