Okay. So I've got an idea for an ACS function to be added in Zandronum.
I'm making an Achievement mod for Zandronum which is supposed to support both single, and multiplayer. At the moment I am using worst's MODCVARS.acs function to be able to save the achievement statistics to the ini. But it's really hard to get it to work with multiplayer.
So how about adding like 'SetUserCVar(player_number, cvarname, cvarvalue, archivecvar)' and 'GetUserCVar(player_number, cvarname)'?
It would be really useful.

Thank you!
