Sebastian Phoenix has been tinkering away all weekend on a plan to raise the User Shop Limit to 50,000,000sP per item. He worked very hard, and the Subeta Senate passed it without any problem, as long as it continues to benefit the economy.
For those of you will run around screaming like you've just had your heads chopped off that this will ruin the trades. The trades are for trading. As in, items. For items. And other items. And maybe sometimes.. more items.

I like it better this way. Like Xarii said, you won't have to wait forever for the user to accept your offer.
