Under a given forum topic, I want to set 1 post Max including any message & reply

I’m on free hosting & wanna create a feature where per forum topic, users including the topic creator can only put 1 post(/message) max
What this looks like: Topic creator cannot reply. Under that topic, other users can only post once under that topic. So they can only reply to the creator, & once.
All responses visible publicly though

I searched all settings, & there doesn’t seem to be a way to achieve this.

  1. But is there a way to natively do this?
  2. I wonder if this plugin restricted-replies can do this?
  3. Other plugins/workarounds people can think of?

It’s better if this feature can be limited to a category of topics. If not, if this can only be done forum wide, I’m open to creating a separate forum just for this

Not quite what you want but how about slow mode as a workaround?:

Ha. That’s a great idea, I’ll try it & see if it could work, I’ll get back to you & update here whether it does. Thank you

It’s not perfect as the granularity is category level. But give it a go.

After playing around with it, yes, setting this at the category level doesn’t help as it disabled users from posting in other topics

But this was better; setting it at a topic level, however…

This requires manually setting it on each & every topic. Can this be set as default for all topics? I thought of the Automations plugin but it’s not in the free plan. Any ideas for setting this on a free plan?
