If I’m confident I will always remember my password, I’d prefer not to provide my email address, because I’ve seen it get leaked in past data breaches.
If you are so, how do I put it, umm "
uncomfortable" at using your own email address then why not just make one specifically for bitcointalk and then use that, just as acroman08 suggested.? In that way even if there were a data leaks in the future, you email wouldn't have any personal information, since it was only associated with this forum.
And to be honest, if you staked your address email wouldn't be an issue. AFAIK, it is only used to communicate with the support in cases of account recovery. And if you lost it somehow, you can just create another account, namely "Skjadoon_recovery" then sign a message, send message from recovery account to the team. If everything checks out to be ok, you'll get back original account.
