It would be really helpful for newer runners of the game to have a little "?" or "what is this?" to mouseover on the run submission page and figure out what that variable means (we could type a short description for each variable in the game settings). It would especially be helpful if you're using acronyms for the variables.

That's a good idea, a work around for now is adding a description of the variable to the additional rules part that you get along with the variable. [This is shown underneath any existing rules given in the categories section, and does not overwrite anything]
