Just curious - when I click on some posters’ profiles, there’s a field for “Last Activity Date” which shows when they last logged on. But some other posters’ profiles don’t have that info. Is it something you can turn on and off in the User Control Panel?

I’d hazard a guess that the ones that don’t show a ‘last activity date’ are the ones that have selected ‘invisible mode’.

That would be my guess too.

Interesting - thanks. Didn’t realise that was part of the “run silent, run deep” option.
