Actually, I sort of found the answer I was looking for (quite by accident) in the thread where you discuss creating a field and converting it to a link.
I was trying to understand how I might point people to web sites outside of the app.
It’s all good! :-)
I’m writing a short book / tutorial to document my findings as I go so that hopefully others will have an easier time learning how to use Decker. I’d be grateful if I can get other eyes on the mini-apps I’m building and the accompanying text so that I’m not mis-stating / mis-representing things.
