Oh my god. I'm so sorry. Haha. No, I haven't played around the LinkCrawler yet so my reply was just a general rundown of how I think the site seems to work in response to your "Without example URLs it is hard to tell whether or not that is possible." comment. I wasn't making any comment or questions about setting up the LinkCrawler (at least not yet lol).
But appreciate the additional explanation though. Might save us both some time in case I finally get around to it and encounter some problems.
