You should provide a valid and active email address. Otherwise, the activation E-mail will bounce back to us. Some ISPs block emails, so you should also check your spam/bulk folder and look for email from support [at] merasangeet [dot] com. If the email ends up in bulk/spam folder, add support [at] merasangeet [dot] com to your contacts, so future emails (password retrieval) do not end up in the bulk/spam folder.
