Hi
I'm working on integrating the API into a script that just follows a user. I have used http://twitter.com/friendships/exists.$format?user_a=$user_IDAa&user_b=$user_IDB and successfully gotten the response of true or false... but as soon as I try using, http://twitter.com/friendships/create/$user_ID.xml I get a 400 error. Would this be a rate limit issue? I'm using php with curl... Is this a rate limit issue even though I can still use the other method without error?
