Spanish Ahora recommends these sites as supplements to taking a Spanish class:

Great Texas University site that includes wonderful video tutorials for all levels: Spanish Proficiency Exercises

Roxxem is an excellent way to learn Spanish through music.

Word Reference.com is a superb online dictionary that defines words in English/Spanish (and vice versa). They also have a Spanish dictionary for hispanohablantes. It's a wonderful service.

"Notes In Spanish" is one of our favorites. They have wonderful podcasts and transcripts through which you can learn about Spanish language and culture.

For advanced Spanish speakers who are looking for more challenging grammar exercises, we recommend Colby University's BK Nelson site .

At the RTV website you can find an incredibly comprehensive selection of podcasts and RSS feeds of various Spanish language programs that are broadcast through Spanish television station RTV.

Duolingo is a relatively new app that helps students reinforce their Spanish sentence structure knowledge. The app also helps in honing the student's translation skills. We feel that it is a great supplement toward learning the language
