I don't think your face change has anything to do with guild invites or group invites (you also don't get notified if someone adds you to their Friends list). You probably just got them because you went into a major city, where people were advertising their guilds. trust me. in every mmo i played, i created female toons for my nieces and grand nieces and someone always complements or tries to pick up or hit on toons. in swtor, one time, the guild master followed one of the female toons around for 2-3 zones like a stalker and liked skimpy outfits on it of course, my niece and i reported him and he got banned. another guild master didn't want my toon to quit his guild. he couldn't give my niece and me a straight answer. in rift, the dwarf female is the most ugliest character you can create and guess what after 1-2 hours of playing with the face slide bars, i created a beautiful female dwarf toon. several players told me they never seen a beautiful female dwarf toon until now. some wanted to know my successful character creation settings. on gw2, a female asian toon with a robust body, a chun-li long pigtail hairstyle with ribbons as hair pins, black hair with dark red highlights named katsumi with my luck will get attention.
