As per said in #unreal-support I decided to open an issue so we can keep track of things.
This is what I was thinking about what to put in the config file
// Rest of the set block goes here obv, like kline-address, network-name, etc
pmdelay_isauthed 0/1; // if the user is identified (1) let them PM right away
pmdelay_servicescheck 0/1; // check if services are online? Yes = 1 or No = 0. disallow any user (probably just fresh connections) to PM before pmdelay time if set to 1 and services are currently down
Closed because module no longer exists.
