"Built on Sand" is my new project; a text-based game that aims at combining the creative freedom of classic play-by-forum RPs with a more active influence of the GM - so that there's a plot going on, NPCs that react to your actions, etc. The setting itself is the very indirect byproduct of another project of mine, that one based on the Cthulhu mythos. I kept part of the themes and setting, however doing away with anything canon, and other whatever other literary influence or random brainchild I liked.
Google! I was looking for all sorts of RP-related fora, in order to contact potential players. There are, indeed, resources made on purpose, but it's good to branch out.
