account from before our [integration with ShareLaTeX to create Overleaf v2](https://www.overleaf.com/blog/518-exciting-news-sharelatex-is-joining-overleaf).

You now have two Overleaf accounts, one under #{opts.poached} and one under #{opts.to}.

You may wish to log in to Overleaf as #{opts.poached} to check whether you have projects there that you would like to
keep. If you are not sure of the password, you can send yourself a password reset email to #{opts.poached}, via
https://www.overleaf.com/user/password/reset

Once you have downloaded your projects, you may wish to delete your
#{opts.poached} Overleaf account, which you can do from your account settings. You will then be able to add
#{opts.poached} as a secondary email address on your #{opts.to} account again.
