Haven't tried that, although actually putting it near the report form could be very easily done.

Great idea !!! Installed.

In fact, cheat-master30 gave this link just after I've suggested something at Vb.com because getting all the time report messages that was supposed to be reply messages from my users.

If you have same thing like me and want to take a look, may be add some comments at vb.com here it goes: http://www.vbulletin.com/forum/showthread.php?t=290828

I agreed with the above poster, and still can't see why vBulletin didn't have this as a default feature in 3.7, let alone having to wait until 4.0 to add it.

Just giving some more feedback here. After our discussion at vB.com and installed this mod, also combined with changing the regular phrases like 'View Conversation' and 'Report' to buttons I had no problems at all in getting fake e-mail reports that users intended to be a regular reply.
Great idea for sure and I recommend.
