Ok, I've just worked out how you can add your own accounts, so you can post as yourself.

At the top, click on New Post, then on the new page click on Dashboard (ignore the new post for now).

Then on the page that comes up, click on Settings.

Then click on Permissions.

You will see a section saying Blog Authors. You can add yourself in there.

Good luck. A gold star to the first to do it!!!!
