Marek Konieczny, DH9SB developed a plug-in for WordPress able to publish a widgetized-log-search on this kind of platform. In the last 5 years, WordPress was chosen by several dxpeditions of various sizes as beast platform to build their websites. Also an impressive amount of radio amateur are using daily WordPress to run their personal blogs.
This plug-in totally free and open for hamradio purposes.
