Ok, I'll keep an eye on it... Maybe you are narrowing too much the concept of advertisement, you see people don't even have an idea how your face looks like yet they get here and engage with you. Advertisement is not only about being on the frontline greeting important fellows or answering questions for an interview... Just be influencing people to behave in someway (for instance go out there and bring some new user, educate him properly about how this place works and give him/her all the tools needed to enjoy (or go crazy lol) with the experience of being here... otherwise I will downvote your account into oblivion lol... That's something I would expect coming from you (Do not shoot me with this one, I have tried to onboard many on Stee, but the shithole that place ended to be drove away most of them again)
Edited: IMO community owners should be the ones responsible for organizing these kind of actions, but then again we need someone who community owners are willing to pay attention to in order to make it happen.
