If you are a fan of Twitter there are some fantastic organised chats available for discussing ELT. They usually have a predetermined topic to discuss and using a particular hashtag allows people to follow the discussion.
These chats are a fantastic way of keeping up to date with contemporary English language teaching practices.
#asiaelt is specific to Asia, but is open to all who is interested. Its run fortnightly on Tuesdays @ 11am & 4pm Thai time.
#eapchat focusses on the teaching of English for academic purposes. Its run on the 1st and 3rd Monday of each month. Check eapchat.wordpress.com for start times in your location.
