You can still log into the old system via this url.. (
http://admin.teenrevenue.com/YOUR-ID-Number/members/ ) However logging in via the front page takes you to the nats set up.
So far though I'm not being very happy with my ratios since it was switched to NATs. Another issue is I'm seeing no rebills under the nats admin and there isn't even a place for them.
Hoping they get this all worked out soon and I hope it really wasn't sold.
