One Article Needed Urgently

I need two (2) articles, of approximately 4-500 words each. One should explain what RSS is and why it is used. The other should be for those who have never used an RSS feed reader and explain how to use RSS. I need the articles today, if possible. You must be a native American English speaker - absolutely no exceptions. I will reject your work if you write with poor grammar and sentence structure. Your work must pass copyscape and I will retain full rights to all of the completed work. Please attach a sample of your writing to your bid via PMB. I will choose a writer quickly.
