When we started looking for a new house we set up an email address houseclark2011. So that all of our house related e-mails would be in one place and to ensure we could switch it off once we'd found our new home as you do tend to get a lot of spam. In hindsight it should have been houseclarksometimeinthe21stcentury.
We also have a wedding account weddingclark. We weren't pessimistic enough to put a year after that though
