I'm not sure how you have reached the editing screen you are using but it's not the right one. From the Forum's home page go to
Options > Application > Edit name & description.
EDIT:Ah! I see you've used:
Options > Application > Change title & metatags
This alters the HTML code that affects code in the invisible <head> tag on a page. The "Title" field affects what is shown on the tab of your browser and the metatags field affects information used by search engines and similar web crawling software.
