update your fork of the cohort blog before you issue a pull request...

[rubyonrailstutor]

now that @agooninz has had his updates to the cohort blog merged, your fork of the blog is going to need to be updated.

review this stack overflow post, http://stackoverflow.com/questions/19884206/git-update-forks-master-rebase-my-branch-onto-it

try to understand how to update your fork so that it reflects the changes that have been made to the original repository since you forked and cloned it.

go ahead and try to update your fork as written in that stack overflow post, the instructions aren't so tough but wrapping your head around what is going on might be a little tougher. when you are ready, issue a pull request with all the relevant changes, ping me whenever you get stuck.
