Server suggestions....

I didn't check this, ever

Good find, Jo. It would be best to have it somewhere around 15 minutes.
I haven't played a lot on public servers lately and I don't know if there are
still players like Oscar, who joins on Wednesday and starts playing on
Saturday

Ok so we can experiment with this, maybe on temporary private server.
I tried it today on justice server but we need to find out which value would be 15 minutes because I set svcmd maxinactivity 20 and was disconnected right away, so it's like it is in millseconds lol.

I did experiment on TLC server and the setting is in seconds.
So setting it to 15 minutes would be the command svcmd maxinactivity 900
To turn it off svcmd maxinactivity 0

I have been going through some maps and played them locally and think that map Si2_Mafia-Deal could be added to a Justice config. Once you know how to start the mission (walk to detonator) the map offers some variety to the other Sicily 2 mission. There are no PAK and the incoming tanks don't always end up in the same place. I have found no bgs on this map.

We could also consider adding Afr1_Underground. It's not the most spectacular map but again offers variety. I found only 1 bug with 2 soldiers shooting through the wall in the hangar on the right. If a modder would be able to fix this bug and maybe add another moving tank that would be great. Also, a few more soldiers could make it more challenging. The underground part could also do with some patrolling soldiers.

What do you think?

Sounds good,but I don't have this two maps Can you send me link for this ?

you can find them here: massive HD2 archive = coop mods

Be careful what you use and install, all at own risk, sometimes textures may get changed and it can be a lot of work to remove them. Or you have to reinstall.
