I haven't seen this MOD posted, but I thought it could be valuable. As users often post links to their own websites, this prevents your forum from sharing your page rank with moochers.
In the file inc_func_common.asp, there is a JavaScript function at the very end of the file (this is the last 27 or so lines).
Replace the exisiting code with the following:
If you look carefully, the only thing I have added is rel=\"nofollow\" to several of the links.
As far as I can tell, this only works for links posted in the message area and footer - if you allow users to post a Homepage in their profile, the homepage icon (displayed in their post) will not have this rel="nofollow" attribute.
I'd love some feedback on this MOD - let me know if there are more suggestions. My site's forum (http://www.whyilovechicago.com/forum) implements this MOD, so you can see it in action (although, since it's new, I don't think any users have posted links yet). I have also used this MOD on my former company's forum (http://www.fathomseo.com/forum).
Thanks!<

Been done before - http://forum.snitz.com/forum/topic.asp?TOPIC_ID=59382#336266<

I figured someone had to have done that before... but I searched for like 20 minutes trying to find it here and I couldn't locate that thread.
Anyways, the post you link to speaks of parsing URLs for hyperlinked text, and doesn't mention the reasons behind using rel="nofollow" in terms of SEO or link crawlers/spiders. Maybe this can/should be listed as a specific MOD for that reason, and not lumped in with parsed URLs.<
