I took courses at gcflearnfree --if you have other sites, please share--and put them with dates in continuing education. Mind you, I was trying to fill a time gap with software I largely knew, but I learned some stuff too. If you are using it to say, learn web-app skills, then applying for jobs using the skills, you're talking a different angle, and the employer will decide if your education is sufficient for their needs.
