Adding simple text in banner

[Caseeno8]

I am using 2.0.13. I am using Temiz theme, got off smf themes and where it says Recep Tayyip erdogan fan club, I would like mine to say Pennsylvania basketball coaches association.  It would be just text.  Or do I have to make a text logo exactly the same as size.  My forum currently says "my board" on top left and want to change it.  I tried putting a 200x200 text logo in there but looked real bad tiny and low on page. I am not very good with computers so if this is not too easy I wont be able to do it.  My forum is www.pabca.org [nofollow] if someone can please take a look. I should be ready to go once I get this done.

Thanks
Chris

To simply change the text, go to Admin/Configuration/Server Settings and change the 'Title'

Thank you so much.  Never looked at server settings before.  Thanks for reply.  Doesn't get easier than that.
