Expertise:  I can answer questions about socially acceptable behavior on the internet, and terms that relate to netiquette. I can answer questions about both email and forum etiquette.

Experience in the area
I'm a frequent internet user and a member of many forums, and I know what people like and dislike as well as find annoying in these places, as well as the type of image your typing style sends to the readers. (i.e. how your typing style effects what people think about you and how seriously they will take you, how much is too much when it comes to abbreviations and emoticons, and what different netiquette terms like 'flame', 'n00b', and 'newb' mean as well as regular internet/forum/email terms)

Education/Credentials
I'm an all honors high school student that spends a lot of time on the internet.
