You've already got buffs, etc... I'd like to click on a players name and send them a sandwich, or whatever. You can do it with a console command, but the convenience would be nice.
There isn't, well.. give just drops items at the players feet. However I know Stompy created a new give command that will now drop items in a players inventory, so... I'll be adding in support for that soon too. Until now (like, today), no one has been able to put items in a players inventory.
