Well, how else are technical writer's are born? If you have any savvy at all in the technical field, and you probably do since you say that you are a technical marketer, than you should be able to do a white paper with no problem. Ok, maybe a little problem at first, but, after you start doing it a few times and you get the way in how things are written, then you will have no problem there. In college, I had to take a technical writing course and I was going for a degree in IA. Now, I could see that and yet, I could not, but, it helps on a resume, especially if they are published...
