I have found that I can always 'cut and paste', even if it is not found under the 'edit' option. To copy the text, highlight it and click on Control and 'c' button. To paste it elsewhere, just choose where you want it and click on Control and 'v'.
As to the membership, yes. You have to purchase membership, the cost is based on your annual income. Membership gives you access to the member forums, where sometime people post more personal things (and where some people will stay close to exclusively). It also will give you lower costs for retreats and such, and other benefits, such as the newsletter and the member guide.
I hope that helps you.
