Ok, since there are still a good amount of battles left and I'm currently too busy to sift through this stuff since I'm on a business trip, I will extend to this Saturday, the 10th of June.
In the meantime, if you're in a situation where you have an opponent who never signs on, please send them a PM again indicating your desire to battle as well as sending me a PM with information about their (lack of) activity. In the PM, give me their forum nick and Netbattle nick if you have it, their last forum activity, and I will also try to check their recent Netbattle usage. If at the end of the week it is clear you are making and attempt and your opponent is not, it will be an easy decision for me to make.
