FIT-or-FAT is a purely private, non-commercial project. There's no big team here, no customer support, and no automated ticket system — just me.

If you have questions about a compendium, found an error, or want to discuss scientific additions, feel free to email me directly.

Since I run the site and the research exclusively in my free time alongside my main job, please be patient if a reply takes a few days.
