Modelpedia is a prototype and it is not finished. Findings it has missed, records it has got wrong, and ideas about what it should become are all welcome.
A suggestion sent as an issue on the repository becomes a public record with an address, which is the better route if you want it to be citable or if you would rather write it in the open. Both reach the same person.
Plain mail works too, at modelpedia.project@gmail.com. If you write it yourself, name the record or the source you mean somewhere in the first few lines.
