In the StaffCP -> Layout -> Templates tab, each template has a settings button. If you click on this, there should be a way to set permissions for the template.
Then, if a user has permission to view more than 1 template, they can set their own template in their user settings.
You have not uploaded the custom/panel_templates/Default/tebex folder from the Tebex module on your computer.
If you get an issue like this, please contact your web host for support with connecting to their database.
You can add the Nameless files straight into htdocs, then when Apache and MySQL are running in XAMPP, visit localhost in your browser.
Thanks for the suggestion! I do want to improve notifications for a future update which will include email support.
I hadn't considered the ability to watch a forum, that shouldn't be too difficult to add. Currently it is possible to watch a topic (the Follow button at the top), which will give you an alert and also a desktop notification if you have the site open in one of your tabs.
