As while testing some GTD solutions I was using Nozbe for some time – I sometimes get their newsletter regarding Nozbe or other interesting GTD stuff. In latest newsletter there was an introduction to 1st issue of their free Productive! Magazine. I have downloaded it and it is great ! There is an interview with David Allen (the creator of GTD), a lot of nice articles regarding task and time management like Zen To Done, personal development, productivity tricks and so on. Give it a try, it is worth it :)
