Someone should make a sticky thread to report all typos and odd grammar in. Everyone can just mention it in there and Mr Dev Face can add a strike through to the text when he has changed it. He could delete it when they new patch is out.
I would do it myself but requesting stickies on my 2nd post would come across a bit presumptuous.
Anyway...
When entering Junkyard (Fallout junktown reference?) Archie suggests that I "thread carefully", I did have 40 points in tailoring at the time so that's a given. Guessing he meant "tread".
