Beyond the Borderlands
All of your characters in theory are on the same side. That said, they are adventurers and all striving for their place in Legend. Sharing information through game summaries, email, forum chat (there’s on here, which is probably a logical place).
Did you find a tomb in the woods of unspeakable spookiness? Do you let everyone else at the Alehouse know or keep it to yourself until you can organize another group to go and kick in the doors? Pulled the wings off of all the Faeries who were defending their grove? Let the rest of the adventurers know how tough you are by writing up an adventure summary.
