Welcome to PIF! It's always great to have new members
This group is about sharing and giving, helping each other out. Sometimes that is in the form of ecigs, juice, equipment, encouragement, and often just support of each other. Offering a helping hand, or a shoulder to lean on. It's complex.
It's true, sometimes the actual PIF thread (where we originated) seems like a general trading thread, and it can be. Yes, I participate. Do I need the juice I take? Or the "PIF offer" I take.. probably not. Personally, I don't like the vendor juices. But I definately DID need it at one time, when I first started here. So why do I participate now? To add things to the newer members posts, to perhaps move the thread along, keep it going, so to speak. Or maybe to pick up something that I know someone else would like, or maybe I would like to just try something I see.
It doesn't really matter why. I try and give back more than I take. Doesn't always happen, but I think, for the most part, we (our group as a whole) do try and "pay it forward" when we can. I think we are an honest and giving group, and I love to see the new members grow into the old
If I am really looking to help someone, I keep my eye on the "Wants and Needs" thread. There you will find the people that need something; to hold off till payday, because a dentist bill came due, because they had things stolen. Often people will post a separate thread, stating exactly why or for what they need.
Will you really know if they are honest, and telling the truth? No. You won't. Even if they have been a member for a while, you will never really know (unless you can drive over to their house and see them face to face... even then, we never really know another's situation unless we walk a mile in their shoes)
So, what do you do? It's purely a leap of faith. Sometimes you will be taken advantage of.. odds are, it will happen. But in order to survive and thrive you have to take that leap. Believe in humanity, and trust that karma works, the good will get the help they deserve... for if we don't do that, then we are not only denying those that truly need our help, but we are denying ourselves as well.
