Over on the forums of Some Other MMORPG, we had collected a variety of useful articles on roleplaying from a variety of sources, which would be useful for folks first learning [or continuing to learn, as we all do once experienced] roleplaying skills in an mmorpg. The things discussed would be as useful in this game and setting as in that one. Hopefully they will prove a useful addendum to the guide above.
* Guide to Why RP?: or Why we talk funny
-- A look at the history of roleplaying in on-line gaming, and how to get involved in the hobby.
* On the Application of Power (in roleplay)
-- A look at the social dynamics of power, and how to use them in roleplay to craft interesting and entertaining stories with verisimilitude.
* [archive] [guides] Just what is this "DM" job anyway
-- A collection of not-setting-specific advice from across a variety of well-written guides, for those looking to try hosting and running events and storylines for others, and for those looking to attend events and storylines run for them by others.
* The concept of the Character Toolkit
-- A look at how wardrobe, weapons, and also mounts, vanity pets, path, and so on can help to express your character concept to those around you, and demonstrate how your character fits into the narrative that we are all building together.
