Well a lot of my volunteering has been right here LOL but I've done some real life stuff too.
I live in Australia so it's probably different but we have a big volunteering website for the state...you pick the areas you have expertise in or want to work in...put your name down and wait for contact, or ring the numbers provided...I wanted to work in music (old people's homes, children) but I ended up volunteering mostly in museums and libraries...my other former career. I did do some charity shop work tho
Helping others really helps me to get out of my own head - it was a refreshing perspective after 20 years of alcoholism....it feels good to do something constructive, and not expect rewards - although it is rewarding to me personally to actually give something back
