Cool, yeah, but I do want them to put forum links.
I think that's my best option as of now. I tested this, and the forum URLs work, but if they enter a classifieds URL, it just doesn't link the comment. They get purged later anyway, so no biggie. I just wish I could require the field and it work this way. The problem is it triggers "The deal link is invalid, please correct it" if they put a classifieds link. Is there any way to remove that validation? So I could require a link, with the Forum setting, so forum links would hyperlink, but the others just wouldn't work? Because that's not really a big deal, since they get purged, but the act of putting a link will keep it more honest.
Or maybe remove the validation and both links would work?
Thanks a lot for the help. Appreciate it.
