I have a client running Gossamer Forum. His members frequently post links to a particular retailer. He's set up an affiliate program with this retailer, and so that he gets a referrer commission on purchases that originate from his site.

What he'd like to do is go through all of the posts on the forum and add his affiliate id to the existing URL tags. I've come up with a short script to do this, but before I run it, I want to make sure that I'm not going to hose anything.

Is there any harm in updating gforum_Post.post_message directly, rather than via the web frontend?

thanks!
