The main Tux Reports website is being updated to the latest version of XenForo. During the upgrade, I took the opportunity to make changes to the redux framework, the files for posting threads, as well as finding a few issues that still need to be ironed out; e.g., if the WordPress and XenForo user have different email accounts then a getProperty null error occurs.
As you should know by now, I'm knee deep into learning how to teach physics at the high school level. It's been a huge change in my career and one that I love. It does keep me from looking at this WordPress plugin. As I've always said, though, I use this plugin and so development will always occur. It's just not at the pace we'd all prefer.
I don't have a release date in mind for this cleaned up version. Lifetime license holders will be able to download it but I can't promise any tech support. No one new should purchase this plugin -- really. I can't support you and it isn't fair. There are developers who continue to use the plugin (surprised me!) and so I'm sure you'll be the first ones to want to see the code changes and try things out.
