I don't comment in general anymore and haven't said anything re: the forum shutdown. But that's because the transition to the new forum has been practically seamless with most of the regulars having made the migration. And with pretty much everyone there already, there wasn't need to say "goodbye".
We're not losing anything with this forum; I can't remember who posted it on the new forum, but someone pointed out that it's WE, the membership, that make the actual forum community, and now we have our new home, one without the onerous landlords.
IMO, there's no need to campaign to save this place. This is just an (internet) address that will be vacant/demolished soon. The community and its spirit lives on in it's new home.
