I assume there are some nice simple guidelines or packages to do this from PHP, but I haven't found them yet. Can anyone give me any pointers? I just want people to be able to sign on from my website and post to twitter. I guess OAUTH would be the starting point, if it's ready. The API seems to be in flux right now, and I don't know what posts I find on the web are currently valid or outdated, so any pointers much appreciated.
