I guess what is really confusing is that, you click on the Chat button, and it says “Personal chat”… then I send a “message” to the discobot and it ignores me. It really seems to me that this would constitute a “personal message”… however, I realize that the term personal message has a completely different technical meaning here. But without a comprehensive manual that explains these things (that no one will read), it is very confusing to use the same terminology.
Further confusing things, in these “personal chat’s”, the chat refers to “Showing all messages”… but these are not “personal messages”…
Note: neither term is clearly defined in the Discourse New User Guide.
