As we have gotten a new tool for this in the Trade Reference tool, I would ask that you not only use this in the future, but that, if you can, go back and post it for past transactions as well. I am going to go through all of those reference I have posted, and do so this weekend, and urge you all to do the same, so that this system gets off to a good start.
Edit: Ok, I went ahead and did a start of this, so all those that have traded with me should have gotten a PM to the effect of me asking you to post a reference on the new tool
here. If I missed anyone I apologize.
