I've had a look, and I've noticed there is no markup guide for TD. It'd be nice if we had a text link in the sidebar to a guide. (The only reason I know of some markup is due to our days at our previous "abode"). On a tangential note, I find that the text in text posts disappears, unless I log out. This happens if I use Firefox, Safari, or Chrome. Purging the respective caches does not solve the issue. Anyone got any ideas why this might be happening?
