I) All auction, buying, and sales threads should state which forms of payment are being accepted/offered, for example "TC only" or "high-value items".

A) Auctions must have an end date or time with GMT (I.E. 25/Dec or 24 hours after last valid bid), minimum (starting) bid, raise and autobuy.
.....II) The original artist of the set when bought from someone else. Always credit the previous owner of the set/texture.
.....III) Whether or not you are willing to recolour the items and how much it would cost.
