posting the code will be tricky as a) i dont have github or sourceforge accounts (yet) and (b) there is way too much to post in text it would bust the forum limit. Also there are files / folders to be removed from the original etc...It's still a "work in progress"
My plan is to get the xtra bits working, do some more testing on it, then maybe post the whole thing as a zip to a public form once its stable...I will keep you informed if / when i do - thanks for your interest - might be useful to have someone else test it (not sure what the rules are here for publishing / exchanging email addresses etc)
