Wikipedia

I have used Wikipedia before to learn about a number of topics. It's a lot of fun to explore this online encyclopedia that is user-written. My username is Prairiechick and I edited a sentence or two on PVLD page for grammar. One needs a bit of caution, however, when using Wikipedia. It might be a good idea to research your question from other sources also but that's the case with most research. What a great tool for the surfing public, though!
