I've seen a hand full of people do that on other forums, and I always thought "get the fuck outa here with your stealth marketing". Those people never stuck around for long either.
You can look on reddit and other places if you see people actively looking for help.
But really I think the best way is to connect with people first and then look for the opportunities, instead of the other way around.
I guess you can't make everyone happy when you exercise your will to ask for help and offer it too; I can understand that.
Thanks for the advice. My challenge now may be how to better connect with the people I might prospect as wanting to help.
