Vista Home Prem, SP2, IE 8.0
Not sure this is an actual bug, probably more a design issue, but here goes:
I just finished a transaction for a pair of boots. The thread that connected me with the seller wasn't started by him; the original poster had posted about kids gear, the seller offered some [that wasn't needed] and I jumped in.
When I tried to post positive feedback for the seller, that page wouldn't allow it because the seller didn't "author" the thread that referred to the boots. While I'm sure the purpose is to vet feedback for authenticity, this seems overly restrictive for that purpose. It would be clear to anyone reading the referenced thread that an actual transaction happened.
edit - title of course should be "Bug or design issue..." not "Bu..." Oh well I've had worse typos...
edit2 - found the link to change title. It's official, I'm a dumbass - just ask my wife...
