This is just a theory, but I think it might actually work. As the name suggest, this type of LD is induced by writing. When MILDing, you use mantra's (sentances which you repeat over and over in your head before falling asleep; take a look at the MILD tutorial for more information). When you write something down a lot of times, it helps you remember things. This is pretty common knowledge, it's used a lot by students. So, this method is simple: you take a mantra which you (could) use for MILD (for example 'I will realize that I'm dreaming'). You write this over and over on a piece of paper. This will probably increase the chance of becoming concious while dreaming. Perhaps it's also a good idea to use this during a WBTB, as this is a physical activity with which you can keep your mind on LD.

What are your thoughts on this theory? Please try it out when you've got the time, so will I. Please post back here whether it worked or not.
