The best online Latin chatroom is SCHOLA, created by Britain's Evan Millner. I recommend this site to anyone wishing to improve his skill in the Latin language. SCHOLA allows you to chat with people all over the world in Latin, in either text or voice chat. The best way to improve one's Latin is to practice it conversationally, and for most of us Evan's site is the best option. To enter the SCHOLA site, click here:Enter SCHOLA Site
