Concerned member here
The way I see it there are a few different major categories of threads/posts to be saved (that haven't been saved by the mods/admins already):
- Mat/Pat Threads + Mat/Pat Compendium
- Tournament Threads + Tournament Listing
- Guides as well as the Hall of Records
- Random posts with useful information that don't warrant their own thread
The big ones are technically easier to do because a few dedicated people already did all the work of collecting the relevant posts (tournament list and mat/pat compendium by @Pb_pal, SPF links thread by the mods), just have a moderator or the original poster edit the post and copy the message over to the new forum. (well, easy in theory, still
lots of work in practice

)
The random posts are much more annoying because they are often part of short conversations or standalone posts in a large thread like the old 'Anything Goes D2 Lounge'. Those can easily slip through the cracks if nobody remembers them.
I'm currently combing through my old posts in the Lounge in an attempt to sort through what to save and I'm finding myself leaving a lot of stuff by the wayside. But there are certain things that aren't available anywhere else on the internet, like
this conversation where fruit and I talk about the exact mechanics of gold drops. (yeah I know, it's a tad specific

)
There is a wealth of interesting posts on game mechanics by inactive members like RTB, Thrugg and fruit that would be lost if we don't migrate it. For posts by such long inactive members (or those who are still in touch and give consent; already asked fruit, answer pending) I want to create a sort of 'Wisdom of the Ancients' type thread where we collect their posts either as screenshots or just as texts. The first post would act as an index.
Active members could repost their content in this thread as well and it would be linked in the start post. Of course not everyone is in the mood of finding (old forum search is broken) and then copying their old content so that's a different can of worms.
It would be cool if all of this info from single posts was ordered and added to the corresponding guides in the future but that is a differnt story, this is about collecting info for the time being.
Sorry for the thread hijack, to keep it slightly on-topic: Maybe we could dump all of these posts/copy&pastes in a separate subforum until a thread is ready to consolidate them. In other forums (not necessarily D2 related) there are special subforums were people can 'test' post guides and other big posts. Basically it would be giving everyone a place to post all of their stuff (whether new or old) even if it's unfinished.
