Now, there are always different ways of looking at the same thing. I for example have redirect boards on my forum, some visible to everyone, some to a limited audience, and each and everyone links outside of the forum. But, they are all related to the community none the less - things like a swagshop, webmails, photogallery, even some server tools, so on... some in subdomains on the same server, some in completely different locations. They are an easy to way to to offer links based on group memberships on the forum. So, in short - I'd agree, url would be better for me, but then again - iurl could be someone elses preferred option. I think that would make a good option to the actual redirect board settings, so that you could decide this by board.
