During maintenance tasks to occur in 2 weeks, User accounts older than 3 months which were never activated, will be deleted.
Some people register but never get to activate their accounts. This could be because the activation email goes to their Spam Folders, or because they provide invalid email addresses. In such cases, accounts end up being deleted by the system after 3 months.
If however you created an account and never activated it for lack of opportunity, please do so before 3 months pass, in order to avoid having to re-register.
Thank you for your attention on this issue.
