Hallo!
I took the liberty to mark the Tver Karelian Wikipedia as not eligible: https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Tver_Ka...
It has no ISO code. If it is similar to Karelian (krl), it should be merged with the krl Incubator. If anyone thinks it's distinct, they should try to apply for a new code.
If anyone disagrees, feel free to revert me.
