WishList Member used the WordPress user database to create member accounts.
This means that members are able to view and edit their profile in the WordPress User Profile section. Member can also reset their password using the WordPress Lost your Password option.
WishList Member does not control the look of these pages so if you would like to customize these pages then you will want to look into possible other plugins.
The WordPress Plugin Directory is a useful resource for locating available plugins.
There is a plugin called Theme My Login that may provide the functionality to customize the WordPress User Profile. Note that we did not develop this plugin so we cannot support it.
