Answer to the second question would help me too (remove latest member). I tried it by going to current theme > theme settings > uncheck box "show latest member on board index." But the name still shows. Not sure if I followed the right options.
Here is the latest member who's IP is not showing. manrajjitsingh This has been the same with each new member for the last 3 weeks. It doesn't show when you go into members in the Admin Panel either, it just shows blank.
