All of the solutions for "you're welcome" should be shown.
I was trying for Bononvenu or something... If I saw the answer(s) more related to my own, I could learn from my mistake. When I saw it I knew that Nedankinde was a good idea too.
it depends on the situation. for example in case you hand over something and get a "dankon" for it, "nedankinde" is the best word. in a situation when someone has just arrived, you could say "bonvenon", "(vi) estu bonvena" or something like that for the welcoming.
