Is there, perhaps, a way to make a sister-site or sub-site that holds just html-converted archived threads?
Only basic formatting required to make them readable (bold, italics, font size and quotes [if possible]), no search (forum or Google, etc), each thread has it's own page and each page is an entire archived thread.
Deleted and hidden posts ignored and discarded since the archive is for nostalgia purposes only - same with edit information unless it can be easily included with other formattin info. And stick to only html-page archiving threads that are open to all forumites so that no admin-only information is released.
I have absolutely no idea how difficult or not this would be, just throwing ideas out there.
