How do I delete a trello account when it will not allow me.

[Larry Tardy]

I accidently signed up for a 2nd trello account and want to delete it but I'm not allowed.

Welcome @Larry Tardy 

I guess that there is a 14 days period where you can still revert deletion of your account... 

Here is a complete guide and more information about this

Other thing is that you might be facing a problem where your account is managed by your organization but not sure if this is the case (you would have to verify it if you use a corporate domain)

Hi Larry, :)
Hope you are doing well,
Welcome to the community!!

I hope @Mirek 's answer provided you some clarification regarding the 14 day grace period.
If you are facing any other issue while deleting your account, let us know.
Thanks.
