i dont think someone from olga will get the credit, this is not directly linked to other sites like that. It will not change the song on another site, only on chordie it will change. And I am sure the credit goes to the person that changed it. So you can see in chordie if someone knows how a song actually is or if they have made a mess of it.
And if you do not think someone is right you can click the option to go back to the original.
If you really want to change it that much then go ahead and make the changes thru chordie, or another option is to go to ogla, submit the correct song then direct a link from there to chordie,
