..... and greetings from England.
This forum, for Data Corrections, is the correct place to request changes such as you have outlined or any other data which you feel should be updated/corrected.
In respect of individual fields appearing on profile pages, we would prefer you to use the "Correct or submit additional aircraft data" icon in the top LH corner of the profile pages. Click on this and you will be presented with two columns of data items which can then be accessed by clicking on either of the blue headlines as appropriate.
I will raise a linked profile for the new registration you have advised.
Many thanks.
