MyBB Community Forums

Good morning all,

I'm looking for a Mod That allow me to limit Topics in a specific forum but I don't want to limit Usergroups.
To explain in my forum (Mmorpg /guild forum ) I have a part "application" for people who wants to join us. I'd like  to make a limit of 2 applications at The same time. Like that people Will have to wait that we move closed applications to apply themselves.
i don't know if it's clear. I'm french.
Thank you in advance.
Ps: using 1.8

I understand what you're asking, but this is not part of core MyBB; you will need a custom plugin.
