Thanks for the feedback about "fair use." I'll watch that in the future!
Moderator Edit: While this matter has been sorted out already and there are no issues, unfortunately we weren't able to send you a PM just yet, Megan (due to a setting on vBulletin), however I'll explain a bit about fair use for you and anyone else who is interested:
Basically fair use states that if you wish to quote or include material from a Copyrighted document, you must only use a small percentage of the original document. The exact amount isn't specifically defined and this law has a lot of "grey area" in terms of what's considered 'right' and 'wrong', but generally you can be safe by including no more then a few paragraphs from a long article (such as one approx. 2000 words), and no more then a few sentences from anything shorter then approx. 2000 words. Additionally, as you did, you must always include a link or reference to the original source, crediting the author/copyright holder.
Try to think of quoting text from an article as a way to give a short "snippet" of information about a link you include in a post -- a preview, if you will. It gives people a sample of what to expect when they click on the link. I'm not an expert on copyright law, so if you'd like more information, I linked to an article on Wikipedia about fair use in your above post (post #5) -- you can also find the Wikipedia link
here.
From what you've said in this post, Megan, I don't expect you'll have any issues in the future. I hope you found this information helpful. If you have any questions or concerns, please feel free to send me a private message -- you can

Anyway, please continue the discussion. It's been a good read so far!
