Here are a couple of websites I use with Add-on + basic Generate Press template. Generate Press is my favorite framework for WP.
These websites were a coop. effort and I am not taking credit – these websites were designed by the IT gurus that volunteer their time and efforts. I am apart of this team and wanted to show others the design and way we went.
1st website is: http://prepareforchange.net/
2nd website is: http://communityleadersbrief.org/
Thank You GP <3 for all your beautiful code and intuitive cooperation for such a great piece of software.
