Yes Russ, but even better...
E-mail Mika with your old and new e-mail addresses and he will retire one into the new one....However, unlike D.net, the blocks that enter under the old e-mail will still be separate in reallity, but will be displayed in the total of the new e-mail. Therefore, you can unretire an e-mail simply by writing Mika again🙂.
One drawback...the e-mail submitted will still be the one that D.net receives even though it may be retired on Mika's!
