Import scripts are nothing I want to do as a developer of this plugin. There are thousands of other forum systems out there. Each of them are more or less complex. I am willing to provide import-scripts when other community-members want to share there own developed scripts. But if I develop them by my own and provide them as a fixed forum-feature I am enforced to ensure that they are working all the time with every version of my forum-plugin and the third-party forum-plugin.
This is way too much work and I can’t ensure or maintain this alone.
