Hey there,
As mentioned in the OP
Please take a moment to consider whether the new Event features in the Discourse Calendar plugin made by the Discourse team are right for you. If they meet your needs, we recommend using that plugin. You should only use this plugin if you’ve already first considered Discourse Calendar.
We recommend you use the Discourse Calendar Plugin if you can. We only support this plugin for specific use cases that are not fulfiled by that plugin. Happily, the Calendar Plugin has both features you mentioned.
Yup, that’s this plugin. But, as mentioned, it sounds like you’ve got a good use case for Discourse Calendar, so I suggest you use that.
Internally, we actually use the Discourse Calendar Plugin to organise events for our members, rather than this plugin. We support specific use cases for a few clients, and we’re open to specific use cases if anyone has any, but that’s it.
