The username takes us to your website because that's what it is linked to. You can remove that link. Here’s how to link your WordPress.com username to your WordPress.com blog in your blog Dashboard -> Users -> Personal Settings -> then scroll down to Account Details. Then scroll down to where it says ‘Website‘ select the URL for your primary WordPress.com blog and then save changes.
Now every time you sign into the forum we can all click on your username and your blog will be linked to it. And every time you leave a comment on a blog your username can be likewise clicked and your blog can be instantly located.
This is an active link to your WordPress.com blog http://housesitters.wordpress.com/ You can use the link below on Tuesday to report your issue to Staff. We Volunteers can't help you. We don't have back-end access to blogs, only Staff do.
Support is closed over the weekend whilst we work on improving our level of service. We’ll be back open again early Tuesday, September 6th (UTC).
