If it helps prove I am the account holder, I can add an image of these messages to the Flickr/Brickshelf linked in my old account's signature. Please can someone get in touch, as I would like to post some MOCs I've made over the past couple of years! Thanks.
EDIT: After further research it seems my old Microsoft email account I used for here may have been deactivated due to inactivity, so that's why I can't reset my password now :/
