Stumbled upon this site today. 12manage: All you need to know about management.

At first glance it appears as though it is going to be very useful for those of us interested in management and application of related theory. Even more so with the paid membership but we will have to see about that after some further investigating. Enjoy

Edit: I have no affiliation with this site at all so if this is considered spamming or whatever than please delete mods.
