hello great fellas there,
please i will like to alter the buddypress menu, i want to know how to go about it. for example, if i want to rename the menu items, how do i do that? if i want to remove an item, say ‘blogs’, how do i do that? and what if i want i to align the menu to the left side of the screen, how do i do that too?
thanks for time.
