Create your ezblock whereever you want it, and choose html ezblock. then, click turn off tinymce editor and paste the code. in visible settings, turn all off except for homepage
for title, go to admin>forum settings>forum title
for a logo go to Admin > Layout Settings > Theme Settings > Logo Image URL
if you'd like to center your logo, go to admin>style settings>headers and footers
put this code in headers: <div style="text-align: center;"><img src="IMAGE URL" alt="" /><div>
replace IMAGE URL with the url of your image
