On 8/7/18 we launched the new version of Thanks.io, which has a number of new features and an updated plans/billing structure.
If you were a user prior to 8/7/18, you can still use the original app by logging in at http://admin.thanks.io.
If you want to get started with the new version and migrate your existing credits over, you can create an account @ https://dashboard.thanks.io/register .
After creating your account, just use the chat button at the bottom right of this page, and ask us to "migrate" your credits.
Thanks for your continued support and use of thanks.io.
