I use flammable. I agree that inflammable is a stupid word. A synonym with a prefix that indicates the opposite is stupid. Also, there have been cases where people who aren't native English speakers think, logically enough, that something inflammable won't burn. I would hate to be even partially responsible for some disaster arising from that.
Frankly, somebody should set the word inflammable on fire and burn it up! It's also completely unneccesary as a word.
