Question: What is the difference between writing user's and users'. Please let me know? I have seen both the forms and really doesnt know clearly what they mean. Can someone help me out?

Answer: When you use 's it is showing posession.. as in the user's pen was the one that made the mark.   users' is plural possessive, meaning that it belong to a group of users. As in the paper written was a colaboraton of the users' ideas and thoughts.  The English language is very difficult in some of it's possessions and plurals.. good luck and hope this helps
