I've pointed out the problems with Alican's video source. I've removed the listing on the update page and will let the page stay on the off chance that it is part of the update. It will be deleted if nothing comes of it before the next update.
OK, so, there is trouble for me doing the edits. You see, I just got the luxury pack which allows you to unlock the cars used for the games. The thing is, though: That's going to make things a little tougher on me to get the number of stars people need for the races. I can do the rest, though.
If you use the classic editor with source mode, its easier to add photos. There's an option for you to upload photos while you edit; you can upload the picture, copy its file name, and add it to the infobox.
For a gallery, you only have to find the correct gallery and paste the image name.
