Ok so i know what your thinking "shared lockers, pfft, just use the damn community locker"
But, the reasoning for my idea is that what if, like me you keep all your own belonging in your own locker rather than community locker so you dont share what you may really need, But you also wish to let a friend go into your locker rather than you going in and taking it out and giving it him every time.
I was thinking there could be 2 possible ways to do this:
1. Have another button in your locker that you can select names from and those people can enter and take what they wish.
OR
2. Any one who is on your buddy list can enter your locker.
A whole other way of doing this can be seen at this post http://radioactivecricket.com/forums/viewtopic.php?f=10&t=696
