as you can see it from here, I would like to have all the links underlined in my forum posts because the current theme doesn't really make them nice and easy to see.
Therefore, I've tried to get to the
ACP > Styles > myTheme > PageNav, Link groups and Tabs
and flagging "underlined" wherever I could, cause I don't understand what PageNav, Link Groups and Tabs are honestly
However, it doesn't work at all.. so I'm here to ask for some humble help
