Congratulations, looking great!

One thing, IANAL, but it seems like the license page https://uidesigndaily.com/license (linking to 'Creative Commons Attribution 3.0 Unported') says that it is okay to:

* "Not give credit . . ."

* "Distribute, sublicense . . ."

Whereas 'Creative Commons Attribution 3.0 Unported' says:

* Must include copyright

* That you cannot Sublicense

See: https://tldrlegal.com/license/creative-commons-attribution-(...

As IANAL, I don't know how things stand legally when your license page says something, but the License it refers to says something else, but that might be something to look into?

Again great job both of you and especially your wife! :-)
