mind if i join in, and give some more specific board suggestions?
requests: necroposting SHOULD be allowed ALWAYS, because if it isn't, it means you might end up with an infinite amount of threads dealing with the same requests, obviusly off-topic stuff should be treated like any spam post.
help: these threads should be locked as soon as the issue is solved, so while it's possible to necropost (problem not solved yet) it should be allowed to, because you may have the same issue as the OP.
forumGames: auto-lock, wouldn't it be annoying if some dude suddenly participated in every single "dead" forum game, and [censored]s up your notifications?
and tutorials... ugh these are tough, the reader should have the right to ask... but it's annoying as [censored] to get a notification about a tutorial you wrote ages ago..
but yeah, that's my opinion, take it or not
