I don't know if everyone knows this but, when you login to the forum, you will see a link that says:
View posts since last visit
It will be on the right side of your screen below the login/logout link. You will not see it if your not logged in, and you will not see it if your reading this. (its only on the GDF Home page. This link will display all the posts that are new since your last login.
So, if your having trouble finding posts in the forum, use that link. Also, if your not a member and just browse the forum from time to time. JOIN! Its a whole bunch easier to browse active topics =)
