have the sumday meibe folder and it's not active.
I have a reading context. waiting context.
for project support, I basically use the kinkless desktop* I have a "Pending" folder on my desktop and that has aliases to all projects in the archives.
You can put a read and review folder in the pending too.
The original GTD system is pretty open ended so that you can adapt it to current tech and personal situations. In your weekly review, you can look at the problems with your system, what projects are stuck, why you don't like processing your email, etc. And figure out a solution. You prolly just need a new way of thinking, a new context or folder in omnifocus or a new folder in your file system.
