If you have forgotten your email address (ie. your username) and you are a house sitter, just send us an email from another email account with your invoice number and we can get you back online in no time.
If you are a home owner, we're sorry to say that we cannot remind home owner members of their registration email address should they forget it. This is because there is no information that home owner members can provide that would prove their identity to us as required by our security protocols (as accounts are free). If you have completely forgotten your email address, you will have to re-register as a home owner member of the site using a new email address.
