Moved tto Community Interface Help.
No you don't have to re-register. This is only for people newly joining - a Moderator will have to approve all new members.

You're welcome ;-)
I see one of our volunteers already answered your question. For others who land on this page inquiring about the same thing, all members received the alert in error. However, no action is necessary as you are already a member. One of our goals in the community is to connect you to information but also ensure that this information is provided by trusted members of the community (not spammers and other advertisers) and therefore new accounts are carefully moderated.
