Thanks everyone for the additional points to consider and look up. Thankfully, I'm really good with computers and to make sure I could prove I am up to date, took several short courses at the excellent Mary Ward center to brush up. Luckily, being in ED,doing unsocial hours isn't an issue, just wish TFL had listened to us and not butchered the no 40!! Thanks again to everyone that posted, it really is much appreciated.
