Don't need a quick fix for my site... just reporting the issue so you guys can hopefully fix in the core code...

When someone registers on the site, they instantly get shown on the activity stream. That's fine but it obviously encourages people to go and look at the profile (also fine!)... issue is, if they go looking before that person has actually logged in (quite often the case), then the profile shows a ridiculous 'last login' date (see screenshot)... Hoping some check can be added so that if the person hasn't actually logged in, it would say that or maybe just have a '-' or something against the 'last login date' on the profile.

Hope you can see what I mean! Thanks!
