In that case, then maybe it's just more relevant for people to alter their own link with the extra bit of text (;all) to allow them to see all of the unread post's at least the first time of logging on, although I don't know if the system will revert back to hiding some posts until the 'Click here to try all unread topics.' is selected again.
Edit:
Nothing changed, just needed to try something with 'Super Hide IP 3.2.9.2' as this is the only site I know of which actually shows us our IP address at the bottom of our own post's.
