To hold people over until I get the full updated version with new features released, I’m posting this Interim version that has been tested / updated for vBulletin 3.7.x
There are no new features in this release, it is simply compatability updates and minor bug fixes. There are changes to both files & templates, but no changes to the iTrader tables.

Description:
iTrader for vBulletin has evolved from
Trader Ratings for vB 3.0.x which evolved from
Buy/Sell/Trade User Rating System for vB 2.x. This is a rating system for when members buy / sell / trade items from each other (presumably on a FS section of your forum). It is somewhat based on the honor system since there is no automatic way to truly tell if they did engage in a transaction. iTrader came about because it was a pain to try and maintain a single thread listing good / bad traders and so far has worked out quite well.
Features:
- Rate another member: Positive / Negative / Neutral
- Specify in each transaction: Buyer, Seller, or Trade
- Leave multiple comments about the deal
- Dates & IPs are all recorded to prevent abuse
- Specify a thread URL to the deal
- Advanced URL checking
- Display ratings over time
- Filter based on Buyer/Seller/Trade/or feedback they left for others
- Users can edit/delete ratings left for others (time based limitation)
- iTrader Admins can edit/delete anyone’s ratings (just incase)
- PM notification when new rating or comment is left
- Per-usergroup permissions
- Lots of admin controllable options
