Hi Gordon,
Some forum owners put up a clause on their sites that say that all material posted becomes the copyright of that forum.
Legally, I don't believe this to be correct.
I think the writer of the post (if it is his or hers original material) would still own the copyright.
However, I think one would still have to obtain each of the writers permission before republishing it in an e-zine.
This could be very time consuming on a daily or weekly basis. Unless you got a "blanket cover" agreement with the more popular writers to republish anything they have written.
Just my two bobs worth.
Warmest Regards
Ricky Higgs
