We have today activated the online events tab, so keep an eye on it once in a while. Events will be posted there and won't be posted anywhere else. Hopefully this will bring it more clear to users when events are going on. You can also confirm your attendance there, if the event requires it.
We hope to get this going and do accept certain events to be posted there by the community members as-well, but you will need to ask a SAES member or a CS member to supervise the event and handle the posting.
Happy event hunting!
