Advanced PHP Chat

Hello All, What would be the definitive PHP chat community to join for someone who likes to discuss how things *should* be done, or would be done *properly* as opposed to the ol' "How do I ..."-style discussions? I've never been satisfied with my code just working, I always want to know whether the way I have done something is the right way to do it. I realized that this is, quite often, a subjective debate and subject to many opinions. Sometimes, a good academic argument about how to do a particular thing properly leads to much more efficient or elite code. Thanks, Stephen
