Little feedback Blaine.
I have it installed and working perfectly for vBulletin 3.8
Also, PM me if you need someone to test things out.
Some ideas if you do push forward with improvements:
*Ability to edit auctions after being posted, I seen the ability to edit description, but the rest is no go.
*Admins able to close, or edit users auctions.
Everything else seems 100%... no complaints whatsoever.
