As the title suggests, is it in any way possible to derank players when they join your server?

 

What I mean by this is I want people to rank up on my server from scratch. Most players that play on the server are newbs lvl 1-10ish or so and they quit instantaneously when they see someone with lvl 50 just plop out of nowhere.

I dont think so, but you can set classes and block customs so players from every level are forced to play with the same guns.

In IW4M there's a function setRank() that you could use to make it display everyone as level 1 and first prestige if you'd want, or just whatever rank/prestige. Though I'm not sure if it exists in IW5M's InfinityScript, but if so you could use this.
