Barnes & Noble has quite a few free online classes if anyone is interested (some require payment for cd's etc.). But most can be taken without investing..although they suggest a book of course (they are an onlin3 bookstore afterall), other students will usually be glad to share with you..or you can find the reading you need onlione without paying..or at a library.
I've found it a good way to start exercising the old brain again..you know..concentrating. There are alot of other free online classes..language ones galore that can be fun.
Just join and enroll here:
