Thank you all very much -- ProcessWire looks like it will be fun to learn. I have become too overly-reliant on WordPress as easy-to-implement, but leading to limitations on my ability to personalize a site such that it looks like something other than a typical WordPress site. Same experience on Blogger. Also tried Drupal & Joomla, both of which required too much overhead for what I have to communicate.
I appreciate everyone's helpfulness. I hope to be very active on this forum. I'm a military veteran, and want to build a professional but personable web site that will serve as a platform for me to provide peer support to other veterans who need help. Goes without saying that I don't want to compete with the VA on a compendium of everything veteran-related, but straightforward content organization is (I think) going to be very important. I also don't want to spend more time on web site administration than I do on actual assistance to others.
