I did exactly that and already explained how I handled and helped each of the 89 new users I welcomed in 1 week of work, none of them complained (alltough a 100% satisfaction is also not humanly reachable on the long run).

Each welcome image is unique and aimed at a specific user and is "posted" at the right moment as a kind of "reward" that the #introduceyourself post is according to the expectations of this community.

It takes about 20 minutes of my time to handle an average new user. I am proud of avoiding them the feeling of being alone on their first steps.
