Introductions thread - please say hello!

Hi, the name's Simon. I have always been interested in mechanical signalling, and I'm fairly familiar with the UK fixed block signalling system, but I'd never really dug into the newer electronic signalling systems. I was particularly interested in the Entry/Exit method of controlling signalling, and was searching for details on the internet when I found the link to SimSig. Absolutely astonished with the level of detail and I can't imagine why I'd never stumbled on it before. I've been playing the Aston simulator on and off for about 2 weeks now, in beginner mode with TSRs off and ARS and TORR off also, I've got to the point where I can achieve a score of 98% overall. I'm guessing it's a fairly simple simulation, with most of the trains both entering and leaving via Aston, and only a few trains running the full distance between Aston and Wichnor Jn., and very few freight trains during the peak part of the day. I'm now wondering whether to up the difficulty level a bit (I did try Standard once, but it floored me how I could turn back trains at a different station when a set of points was faulty - I know now, but I didn't think to pause the sim while I went to look for answers and it messed everything up), or go for a more challenging simulator. I'd like to try Rugby as that's where I live, and I used to commute regularly both to London and Birmingham on that line. I'd appreciate any suggestions for more experienced users. I can see there is a whole lot to learn. Cheers.
