The PSTN should be pushing until it reaches the GLAS, where it stops because it has a ctype of GLAS. That means it can't push it. It is stopping a few pixels before though, too early.
OK, but I'll have to test a bunch of things to make sure it doesn't break anything else, since there's a large chance it does. I'll look at it in a few days.
I don't know, it probably stands for Simon T. Robertshaw though. He is very busy with work related stuff all the time, even using one of the tpt servers for that. Maybe he renamed his account so that he could use it at work. (not sure why he wouldn't just make another one, which would make much more sense). Either that or he didn't like the name, but I thought he was fine with it.
Hopefully it doesn't break anything, not sure whether it would. All links seem to redirect nicely.
