Basically this just tells you that the first post of the thread is the first post of the thread?

like it (function maybe?) returns true when the post is the first post in the thread or it returns false when it's not the 1st post in the thread...
or that it just returns the post # in that thread... like 1 for the 1st post, 2 for the 2nd, 3 for the 3rd, etc.

something like that... i hope you know what i mean now...
