It could be the same favicon that shows on phpbb.com and other forums. Same as the phpbb banner is in every style.
The favicon should be placed into the root and be linked inside the head. Like this:
Code: Select all
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
That way people will only have to replace the existing favicon with their own, so no more need in editing the header, into adding that line etc.
