U++

hello,

at the bottom of this page : http://www.ultimatepp.org/srcdoc$CtrlLib$Tutorial$en-us.html

the link Core value types tutorial - learn basics about non user U++ related code. seems not well formatted, and is not working (at least in my webbrowser FF53.0).

I think it may lead to: http://www.ultimatepp.org/srcdoc$Core$Tutorial$en-us.html  and not topic://Core/srcdoc/CoreTutorial$en-us as it is.

and

Ultimate++'s team email upp@ntllib.org as seen here : http://www.ultimatepp.org/app$ide$About$en-us.html
