In its own separate thread for convenience!
There are two main elements to this:
1: Archiving old threads
To clean the boards up a little bit, and to marginally lighten the load on Kareha, the plan is to move all threads that have not seen any activity for the past ~8 years (half the age of this site) to the archive. Maybe with the exception of DQN which can get an earlier cutoff date (or none at all), and I'm definitely doing this for Romance which has over two thousand (!) unarchived threads.
2: Merging boards
This has been a recurring topic for some time, and I think it's about time something be done about it. So as not to have a bunch of barely active boards on the boardlist, and to make the site slightly tidier (and more convenient to moderate), it seems prudent to merge some of the less active boards and the ones that have overlapping themes. My proposal is as follows:
General
Internet
Culture → Media
World
Please use this thread to voice your opinions and ideas. This is also probably a better place to discuss necrobumping, rather than the mod requests thread.
I would like to get the archiving done pretty soon (and it would also be easy to undo at some later point in time), but the board merge isn't all that urgent and the final decision on it can take its time.
Should mergers occur, would it be possible to add little tags to thread titles to indicate which board they originally came from? Maybe it's a bit of a strange idea, but something about not knowing which of the retired boards a thread originally came from stresses me out.
...though in the case the board no longer exists, it should probably say "former Requests (/req/) board" or something.
