I have seen a minor bug just to let you know of.
The PM system doesn't seem to follow the proper time stamp format as the forums.
I sent a PM this morning, but the time stamp indicates that I sent it at 9:03PM. So unless I am a time traveler (which would be amazing) this is an issue.
Here is a screen cap.
Nope! Scratch that! My profile time zone was set to Dublin time. /insertidioticcommentshere
