Yes, it's ok to post announcements of teaching events.
Please note FreeSangha does not take any responsibility for any organization's view or the views posted by any organization. As we are not expert historians or lamas or bhikkhus, we don't discriminate according to anyone's choice of dharma. We simply offer the opportunity for people to connect to what they're interested in, and we're here to foster a friendly environment for anyone interested in the dharma.
Thank you for bringing this question to our attention.

Ogyen.
