October 2012 edit
Hi. Welcome to Wikipedia. Please do not revert valid content from Wikipedia articles, as you did with all the citations from Recurring experts section of the Pawn Stars article. Those citations are there because Wikipedia requires that the material in its articles be accompanied by reliable, verifiable (usually secondary) sources explicitly cited in the text in the form of an inline citations.
In a similar vein, the comment "Yet, that didn't last long" in regards to Corey Harrison's weight loss was not supported by a source.
Lastly, when removing material, please specify a reason in the edit summary and discuss edits that are likely to be controversial on the article's talk page. Nightscream (talk)
