It'd be good to be able to archive or delete a batch of PMs and tracer threads threads at once, rather than one by one. (Maybe it already is, and I haven't worked out how to do it...)
And - I suspect this isn't practicable, but I'll suggest it, just in case it is - if it were possible to do a time warp back to a particular day's threads, that would be fun - it would be a way of finding out if the Mudcat-is-a-shadow-of-its-former-self complaints actually add up to much. (And if they do, it might encourage us to measure up better.)
The messages since last visit - this never works for me, I push it and wait for ages and nothing happens. But it sounds a great idea.
But the crucial thing is not to do anything that would screw up the Mudcat, which is far far better than we have any right to expect. Thanks.
