I might add, that at this stage, an incomplete registration is no better than no registration at all! So ensure yo u enter a valid e-mail address and that it does not get sent to your "junkmail" folder, as is the case with many free e-mail providers.
Unactivated accounts will be regularly removed.
As far as registered users whose e-mail addresses become invalid, you must ensure your e-mail address is valid if you subscribe to any topics. You will recieve a private message if any mail sent is bounced back to me. If you ignore my message, your account will be deactivated and you will have to change your email address to a valid account and then re-activate your account. Use of an invalid e-mail address may also lead to any subscriptions you may hold, as well as your auto-subscription-option from being removed with your authority.
