Damned, I clicked on the Administrator's group, so there was not this option... 
Thank you very much!

In Administration>Groups there is just 3 things : Add group, Set Default Group and Edit/Delete Groups. 
Are you sure?

Topic: Reduce waiting time (4 replies, posted in PunBB 1.2 troubleshooting)
Hello everybody,
First, excuse my poor English because i'm French. Beside, I'm new here and I hope to post my question in the right place...
I'm experiencing the last punBB version with CSD Nantes and I and my friends would like to reduce the time to wait between posting 2 posts. (Because of we flood a lot!)
I didn't find the option and i guess it is possible to change the code to do it.
Is there any Idea to help us?
Thanks.
