Are you on Facebook? -nowadays it is more unusual to find people who are not on Facebook as opposed to people who are on it.
I have just got back from running a Level 1 & 2 workshop. One of the participants was very keen to get an IB Chemistry Teachers facebook group together and has gone ahead and created a group. It is aimed at IB Chemistry teachers and its purpose is to share ideas and resources. You can find it by search fro ‘IB ChemTeach’ in Facebook. I look forward to seeing you there!
