Let's go back to volunteering as astutely mentioned by SQLSister.
True, non-profit organizations will not be looking for vb programming -- why? Because they will most likely not have a clue on what it is and what it can do for them.
Rather, when seeking volunteer experience, look for providing solutions that involve VB. Example, web pages, vb web access to a database, etc. Also, security, data entry, consolidating subsystems....
A executive director or such will be looking for solutions in what you can do for them, not how they can help you gain experience.
