should i say Wanderers Diaries or Wanderers Diary or Wanderers Diary or wanderer's diaries?

hehe getting confused..please help
It's not a silly question. It is one blog, right? But if two wanderers are going to write in it as separate people, then Wanderers' Diaries is a fine title. Notice the apostrophe, however.

thank you for your reply, i thought it is a really silly question to ask, but hey wanted to be sure, well the thing is that english is not my mother tongue and i dont 'feel' when something sounds wrong...


so i wanted to call the blog about two people travelling here and there as a wanderers diaries, but then started being confused about using two plural nouns...is it ok to leave like that? or is it grammatically incorrect?
that is why i started thinking.. maybe it sounds better wanderers diary...heh anyway..thanks for answering even though it sounds like a silly question Emotion: wink have a nice sunday
