I go to my Friends page beta.glitch.com/profiles/PI... and there is a message that Jontezuma recently joined Glitch and I should add him to my buddy list. But Jontezuma is already on my buddy list as part of the Facebook invitation send/accept process so this message is extraneous. The other friend I invited from Facebook today is not listed here, so there may be something unique or delayed about this (the other friend joined earlier in the day so maybe it's timing).
