My e-mail adress is firstname.lastname@example.org. My request to join was declined because it looked like a private domain. It is not! It is an offshoot of kidsafemail.com! Go to the site and check it out yourself! Please! I would really like to join Combine.
Yes, that site redirects straight to the kidsafemail page, so you shouldn't be having any trouble getting approved. If you received a rejection via e-mail this must have been a mistake; please submit a new application and I will try to keep an eye out for it so I can approve it myself.
