I'm not sure if this would even be possible but I'm going to throw out there anyway...

In my time playing on RPoL, I've run across players and DMs that I really enjoyed gaming with and some that, unfortunately, I would never voluntarily play with again. I do try to keep a list of these user names but it is sometimes tedious to try and check them, especially since you can't see the user name of other players in a game...

Could there be a way for each individual to "mark" another's user name as someone that we would/wouldn't play with again?

I'm thinking something like a player/DM I really like would have their name show up in green text while those I wouldn't play with would have their names show up in red text...

As I said, I'm not sure how, or if, this would work as each user name could have multiple "ratings" that are each assigned by different users but I'm kind of thinking along the lines of the language groups where it generates the "you don't know this language" garbled text differenly for each player (and even different for the same player when reloading the page)...

This has essentially been asked for many times over the years, and has always been shot down with an explanation that RPoL will not allow you to blacklist people.

Even if you were using it to put 'good marks' on folks, that would violate the core tenet of anonymity between games.

RPoL has a long-standing policy that if you want to make your own list of other users, for whatever reason, that's up to you to organise and maintain.  We will not provide a system to automatically track other users, or what games they are in.
