Thanks a lot for these tutorials I’ve benefited immensely from so many of them. Also happy to see the new wiki on delegates; just a few months ago I was searching to see if you’d written one!
With so many delegate types, combinations and special macros like BindDynamic/etc I found them very confusing while starting out despite being familiar with basic function pointers. Hopefully newcomers to delegates will find it easier now!
BTW I can’t be the only one who types “unreal <search topic>” while looking for UE4 resources 
Definitely interested in the book you said you were working earlier in thread.
