Some of our content is only visible to registered users; how do you want to handle that? It's our advlt and AlienSlof's (which is mostly advlt, but some isn't) content that's only viewable to registered users.
I would create an account for the bot. I am not sure how I would handle it on my sites side. Shouldn't be too much of a problem though as IIRC your site prompts for sign up with a nice-ish error message and the same thing happens for TES-Nexus with advlt mods.
Let me know how you want the information sorted and we'll get on it.
I have had another quick look and I am fairly sure that I could get the majority of the mods, the one issue being that I can't reliably get the author so I would in most cases just have to leave it as "Unknown". (I would be able to get the author if an entire sub forum was made up of one author, Solf for instance).
If you see the lack of being able to parse author as being an issue (Not being able to would occur when the title isn't in the format "NAME'S mod" or "mod by NAME", basically one of a finite set of patterns. (I couldn't find anything indicating the author in the first post)) then you may want to look into something like the XML that Fligg did. Or maybe something in the first post. In other words, some way to find the author that can be broken down into a logical set of steps.
