Yep, common way to change it and any set variable though it's actually way easier to do using the
URM, simply plop that in the /game folder and editing your game is piss easy, just search the variable you want to change, or, if you don't know the name but know it's value, search by value, boom peace of cake. Using the website requires you to either do everything at once or repeatedly jump out of game, upload save, edit, download save, reload on edited save whereas the URM it just takes about 5 to 10 seconds. Really can't stress enough how fucking easy it is and how using anything else is simply more work and frustration.
Also, to hyperlink, highlight the text and click the two chain link image in the toolbar and add the url there.
