I was using the free trading system offered elsewhere until we hit some snags with bugs that were show stoppers for us and no ETA's on getting resolved.
I purchased Xencentral Trading System after they made an import system to import from the free trading system.
They've been very good with bugs (most fixed within 24 hours) and new features have been suggested by me and others are being added quickly.
Implemented recently
*ability to make additional comments mandatory
*ability to disable additional comments box completely (only feedback comments show when leaving feedback)
*ability to force a thread to be posted from a deal forum (select valid forums in settings)
*ability to set Unique Deal URL (only allow users to leave feedback once per deal thread)
*detailed trading stats (positive, neutral, negative) in postbit
*ability to set default notifications for all members (notify by email, PM or Alert) and when notifications are sent (immediate, hourly, daily, weekly)
And also new suggestions are being made all the time to make it a better system and the developers are listening!
If you rely on a trading system for your site, the support and quick fixes alone are worth the $65. You get what you pay for!
