Alright folks, I've been working on the wiki and here's what i got:
I found a feature which could let me search and replace text by namespace, which allowed me to effectively search (almost) all legacy pages.
I copy/pasted our beloved infobox metaobj template to a new templated called infobox legmetaobj, which is effectively the same as the original infobox, except all legacy items previously categorized in our main categories are now in their own separate legacy categories (found here: http://ringofbrodgar.com/wiki/Category:Legacy)
on top of clearing out our beloved categories, I've also restructured the categories to hopefully be useful. what is now left is putting every object and item into the correct categories AND bringing quite a few legacy pages that were left behind back to into our main namespace. I'm currently wrestling with the idea of how to automatically categorize all items upon page creation, but that's also a lot of work.
We are, however, making some pretty good progress on getting the wiki to tip top shape. finally separating all the legacy pages from out main pages is a huge accomplishment. hopefully this transition will make it easier to use the wiki
and: if anyone has any feature requests, leave a message here or pm me. depending on the intricacy of the task, I might be able to get it done.
