I've been playing for some days now.. what I'm still puzzled about on the char. sheet is what Rec. Remaining means. Says I have 3 and no idea what it is...
You can use your 3 reccomendations to reccomend other players. They have no purpose. But when a player has enough reccomendations, their name starts to turn blue.
You can click on the "thumbs up" icon in your actions tab while having another player targetted.
/eval will recommend another player. You'll notice some players have blue names. You can accomplish this by receiving recommendations. There are absolutely no benefits to having a blue name other than the blue name itself, but "recommendations remaining" tells you how many times you are allowed to recommend another character. It refreshes every so often, though I don't remember how long.
If someone buffs you or helps you out, you should /eval them.
