Hi guys. Just wanted to check back in as the OP and give an update.
I'm really excited to be creating a personal project with PW and am amazed at how clever it is. I had one of those "aha!" moments recently where I opened up the default template, tweaked some API calls and managed to extract content from fields across various demo pages. It occoured to me that I can work with PW and I "get" it. Happy days indeed
Since I posted I had been looking at my options and evaluating both ProcessWire and Craft CMS.
Craft CMS really does have the upper hand in terms of the backend manager. The design, responsiveness and usability are superior (IMHO). To be fair to PW, Craft is a much much newer system.
However, as clunky as PW is I'm really excited to already be building a personal site with it. No offence intended but the back-end of PW is like the Millenium Falcon. Clearly its dated and a piece of sh*t but what an amazing piece of sh*t. You know it wont let you down. Looking forward to being part of the community.
I'm really excited to be able to use MODX, PW and Craft and will use, support and promote all 3 from here on in.
