Join/Log-in Button

When someone is not logged in, the top part of the page will have a JOIN button. This gets confusing for people who are already a member but maybe accessing it on a different computer or have logged out. Is there a way to change the verbiage to say JOIN/Log-IN so they know you have both options by that link.

Mine already says Join or Log in. Which template are you using? I'm using a tweaked version of Evo.
