Other cothers email me when they are posting on or just reading funny, or sad, or wild subjects.
And if I see a trainwreck in progress, I do the same for other cothers.
The good thing about telling others about some threads is that we've saved some horses by donating money, when we'd have not opened the threads w/o alerting each other. And we've helped put some hopeless horses down by donating to euth them. Sometimes happy results, sometimes sad but necessary results.
ETA: I'd never have opened the thread about people deleting their threads if someone hadn't told me how funny it was.
