I've just received a suggestion by PM from a member (no names1) that coincided with thoughts I've been having over the last few days.
And that is to relax the injunction against thread necromancy - temporarily at least.
On the basis that it's easier to reply to a topic/ comment than it is to generate a new topic entirely this may help get things back into something approaching "full flow".
We do seem to be picking up slowly - with the spammers coming nearly as fast as old members return and new ones appear - but, to me at least, there seems to be a sort of "waiting around to see if the site's going to die again attitude" and "is it worth starting/ replying to a thread" 2.
Hopefully opening things up like this may generate more traffic and lead to a full recovery.
1 You know who you are Geordief.
2 On my part too, although I was never much of a thread starter.
NOTE: I haven't run this past either of the Admins so they may overrule me on this, but... I think it's worth a try.
