A common name - as in - a name which is in common usage - part of oral history SHOULD be on iNat so people can search for it.
We can add up to 3 languages for common names. Where I ID in South Africa, I use English and Afrikaans - that helps me when an observer has a placeholder, another clue to get to what they think they saw.
My iNat is set to default to show the scientific name first.
PS collem is also 6 letters and will get you to Collembola (springtails is a common name ;~)
