Kage related this on one of my threads:
"Re: Currently are there any 3DTVs that allow you to adjust the 3D level?
I think I answered it though, pretty well and, informatively. Now, wheres my thanks"
Another website has a spot on it's lower left-hand screen that says "thanks." You click it and a thank you pops up identifying the name of the member who clicked on it.
It's a nice convenience and, more so than that, it serves as a reminder that posters do appreciate thank yous.
