Like the others who have posted, I enjoyed your posts very much. Stick around and keep contributing. I never wanted to even hint at this before now, because, well, why. But I have to say that this outcome does not surprise me. There was always a tone, I'll call it melancholy, in your writing here that presaged a crisis or decision soon to come. I say that only to reinforce that IMO this decision has been brewing for quite some time, whether you realized it explicitly or not, and thus it surely is a solid one that comes from the heart. So, very best wishes to you in your next phase and proceed with confidence - I'll also echo the others who said that I'm sure you'll make your mark.
