Know any sites where you can publish/post your poems or stories?

Answer 1

There are many Yahoo groups that cater for writers. Go to groups, and do a search for writing, poetry, or story writing. Have a look around, becuase many are 'cliquey' groups (ones which have a number of regular contributors and don't welcome new members as much as other groups). But you'll be sure to find one or two groups that suit you.
