Well, I got a few things I'm spinning out right now, Grey's first post along the line of adding additional info to the XML field. (I only have the % of lvl completion to finish, which is quite simple)
And I actually "jumped the gun" and started working on a SG xml feed. It won't be private and won't need the password string in the URI, BUT I also found how to incorporate user's hidden status on both characters and visible characters' Influ and XP, making it so, if they don't want them visible, they won't even be visible here.
Lastly, after speaking with Mav-X... it was decided that the ability to hide influe and xp should be character based, not global, HOWEVER, he brought up the brilliant idea of utilizing both. If you character doesn't have a decision made on weather XP & influ should be hidden, than it will ask the global settings for the right answer. Making the character tier the dominant query.
(Ask IceHeart to translate my geek-speak if you don't get what I'm saying, lol)
