It's true there will never be a WinSEQ released to the public (for the exact reason domosan stated). But that doesnt mean it has been abandoned or not in use anymore :)

Hey guys, just wandered into the #MacroQuest chat room a few hours ago and so far this looks great! i'v had a chance to try this baby out in EQEmu 0.3.4dev (hogiebane) and it works perfectly.. keep up the good work guys.
