Also, check that attitude. The NES members that help me and give me good advice, do so because I either helped them or met them several times at get togethers, NES shoots, group buys, took classes from them ... I can guarantee you that more than half of the NES members on this thread have seen me at least once at an event.

The people in this forum are some of the nicest people I have met. Thanks to NES, I got my first real job after college. I could write several pages on all the help I received throughout the years.
