I do not recall that being available as a member group permission, its only a site wide setting. Not a bad idea to have that as a member group setting.
Yeah, I’ve dealt with this before. On most forum software, the “time between posts” is usually tied to the member group, not individual accounts. A common workaround is to create a special trusted group for long-time or proven members and lower the wait time for that group. Some platforms also let you set exceptions via user IDs or plugins, but it depends on what forum software you’re using. Which one are you on? I can give more concrete steps.
Pretty sure it's ElkArte forum software, since the question is posted on the ElkArte Forum software website.. 😏
Yea, I'll be interested in seeing what "concrete steps" you can offer for ElkArte beyond waiting for a version that supports individual or group posting-delay settings.. 🤔
