Virtual volunteering has many benefits. If you don't usually have the time or transport to go somewhere and volunteer – getting involved from home is a great way to give something back. You can build key skills such as data analysis and research, by taking part in virtual projects and it's flexible so you can give as much or as little time as you want!
Local community, charities and organisations need the support of volunteers like you, and there are lots to choose from.
