Leaning No.
I believe the cons > pros.
I also believe it works well as is. To give an example if one of my guildmates posted something I may want to purchase it. If someone else is able to click faster than me because of a notification then they are able to take credit for it.
It's also my belief that this notification would break part of the cycle of free and competitive trading from forum gold to donor forum stuff. As somewhat mentioned before it may also hinder the ability to make friends or trusted with it. It could also break the cycle in the realistic nature of Patience and Virtue that comes along with a higher user account status here on d2jsp.org.
Well... Notification are used for a variety of things and as I continue to think about it I continue to see more cons than pros. Sorry Epiphany, it's turned into a solid no from me. If you want to challenge my opinion then
