Guys, I appreciate your input, but...
Mod queue is a useful tool for many sites, I am sure. We don't do that, though. It's too much work, and our users should be able to post in 0.1 seconds. This is not a matter of opinion, it's a fact. It's our site, so that's how we
Limiting daily post count to 50 would be - as I said - more than generous. I - as the most active contributor - have never posted 50 posts in a day. So, limiting daily post count to 50 would hurt only one person - and that's exactly the point. And actually I would set the limit to 30, because that 50 is already doing damage. Besides me (and this new user), nobody has ever posted 30 posts in a day on our site. Potku.net is a not a drive-by site. Potku.net is a board where participating in most discussions requires a lot of time and energy. Thus, posting 30 posts in a day would be a full-time job - unless someone posts meaningless posts, which is what is happening right now and which is the reason I am humbly wishing for an EXT. We do have some lighter topics, but there aren't that many of them, and they are not that popular. Our users are, in that sense, serious and in-depth. So, 30 posts a day would not be a problem except for this youngen. And that would be the idea.
There's a huge difference in my opinion whether the system (EXT) does something or an actual person (Moderator) does something. The latter makes it a lot more personal. We don't operate that way.
So, the best and only way to go would be an EXT. Hopefully someone with the ability to code will see the same need.
