01
I found a mistake
This is the most useful message I can get. Almost every claim here points at a source, and a cited source is one you can go and check — if I have misread something, credited an idea to the wrong person, or stretched a finding past what the study supports, tell me where. Fixing it is quick; noticing it alone is not.
02
I want to contribute
A page is missing, a section stayed shallow, the English stumbles somewhere. The reverse counts too: if some part of this described you with uncomfortable precision, knowing that tells me what is working.
03
I want to support the project
The site carries no ads, no trackers and sells nothing — and the intention is to keep it that way. I have not published any donation method yet; if you would like to support it anyway, write to me and we will sort something out.
If you read this far, you have already contributed more than you think.
