Hello Webmaster,
I think there may be problem showing the Last logged-on date in user's profile,as recently i was checking the forum section of 18-Aug-2014 and saw bandi' post,as she posted Sql Server related queries on 18-Aug-2014,but as a go to her profile,her last logged-on date is showing as 13-Aug-2014.I think it must show the last login date i.e. when user gets login into the website.
I do not know,whether this is a bug or not.But kindly check this issue.
