If you are part of the guild, you are welcomed to use them. If you aren't, you cannot use them.
Here are some backgrounds. If you have made any, and would like to send them to the guild, send them by email to me, and I will put them up here.
If you want these background for your shop, copy and paste the first html. If it is for your user look-up, do the same, but with the second html. (You can change the font color with the html given here. Just change the "text" or the "font color" the color you want, and it should change it for the whole page.)
If you put a background, and you see that it doesn't work, please tell me. It just means I haven't put the html code correctly.
