If you have a skill or have information to share with someone who is 
looking for help and you're not being compensated, I would think that 
fits the definition of volunteering...

No one is paying me to offer what little assistance or experience I can 
give to others here. But when I do give support to people normally when 
their computers have problems, yeah, I get something back for my time.
