A quick (clear!) detailed explanation thanks to Shoie13 at minecraft.swgi.org Notes: If you didn't make sign, right click it to buy/sell (depending on the sign type) You need a free slot and enough game money balance to buy. You need the item in your inventory if you want to sell TO the sign You can restock sell signs by selecting the item and right clicking it on the sign to "refill". You automatically pick up any money earnt (or items purchased) at the same time when you right click it. Purchase signs are fiddly to put more money into - you may need to break and replace it to "refill" the money. Only the person who placed the sign can break it, or get stock/money out. If an admin breaks it the balance should transfer to the sign owner automatically. ------------------------------- Selling your stuff to players - ------------------------------- line 1: [trade] line 2: $amount you want:0 line 3: #stack size #item number:amount of item your adding to sign line 4: your name will appear here so now your sign will look like this [trade] $10:0 10 redstone:20 Shoie13 Explanation: [trade] (trading) $10:0 $(10, 0 money in sign) 10 redstone:20 (10 Redstone per $10, there is 20 Redstone in the sign) Shoie13 (who made the sign) --------------------------------- Buying stuff from other players - --------------------------------- line1:[trade] line2: amount item:0 line3: $amount for:amount in sign line4: your name will appear here when you have clicked ok so obviously it will look like this [trade] 1 glass:0 $10:1000 Shoie13 Explanation again!
