> I hope he'll do the same with v3 :)He posted a message to one of the groups the said his take is that Google's tutorials and examples cover everything a tutorial from him would cover (my words, you can probably find the thread if you search). I know that I am still pointing people to his v2 tutorial for help solving problems in v3 (like the dreaded pitfall #3, solved by function closure) and his "Javascript Concepts" pages. -- Larry > > Thanks to both of you! -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
