Is this possible?
I'm a member of a local community group and suggested our volunteers use Trello to manage the events that we run. Stupidly I created a workspace and boards under my personal account. is it possible to move this workspace (boards and all content) to another account I have since created?
You can use the Transfer Tool to transfer the boards from your Personal Account to another account. You can also remove the Personal Account once you have made sure everything is moved correctly.
Here are the instructions for the same - https://support.atlassian.com/trello/docs/how-to-transfer-boards-to-a-new-account/
Hope this helps :)
