A little disclosure on the state of the TL:
As far as I'm concerned, I have not given up on this project, but it has been on indefinite hiatus of late, for various reasons: lack of time from RL committments, mild writer's block, and, most importantly, an erratically malfunctioning home laptop keyboard, which makes it quite unfeasible to write long documents on it. For various reasons, I have not yet come around to get my laptop fixed or replaced.
USAO is my most ambitious AH project to date, with the longest and most complex updates to research and write, and therefore it is the one that suffers the worst from the situation. In recent times, I only managed to write a few relatively short and simple AH scenarioes and make comments & contributions to other people's TLs by sneaking some time on office desktops or, for really short stuff, using screen keyboard software. For the USAO update, however, these stopgaps never turned up any practical. As a rule, every time of recent that I felt some stirrings of inspiration for it, the laptop malfunctioned again, or I had RL calls on my time, and I had to ignore them.
Again, however, this does not mean I have given up on the TL by any means.
