A great way to connect and seek informal professional development is through Social Networking. Here are TWO helpful communities I find helpful and informative on google+
The first one is English Language Teaching (ELT). They provide helpful resources, discussions about important topics, tips for Teachers & Learners of English [ELT/EFL/ESL]. Specifically on here are various articles about grammar, geography, participation, and listening skills. As well as worksheets, information about seminars and teaching abroad.
The second community I found helpful is Teachers for Interactive Language Learning (TILL).
This site is great for creative, sharing, and daring individuals interested in helping others learn English as an additional language! This site has some nice inspirational quotes, teachercasts, material suggestions, and job opportunities.
Both of these google+ communities have great resources and opportunities to discuss questions that may arise in the ESL classroom!
