While I'm rather new to the website, I've picked up quite a bit regarding one particular topic (the Rainbow Servant prestige class for 3.5th edition D&D), and I would like to write this information into a Q&A for other users to read. How do I do that? Just write a series of questions divided into a number of categories in the question (stuff for players regarding what is a Rainbow Servant, what do they do, how to level with them, issues regarding the class and how it affects them; stuff for Game Masters and what to do if a player wants to be a Rainbow Servant, the impact of a Rainbow Servant on the game, how to handle them regarding roleplaying, adventure hooks and so on), then post the answers to these questions in the fields below? Or should I be doing this in another way?
Find real, specific, questions and answer them.
We're not a blog nor a monograph publishing service. When pondering self-answering questions (which we encourage) remember that the questions should be real questions that stem from problems you've seen or are having.
Therefore, find real questions about the rainbow servant, and ask them. Remember to cite the original asker if it's not a personal problem you're having. Or, if you want a lengthy discourse on the rainbow servant, start up a small blog and discuss at length. We don't discourage self-promotion in answers (so long as it's disclosed) and you can simply cite your blog when answering questions that the rainbow servant applies to.
