This is an awesome plugin for Discourse to automate things.
I had a question in regards auto reply:
Defines a list of key/value groups, where the key is the searched term, and value the text of the reply. Note that value accepts %%KEY%% as a placeholder to be replaced by the value of key in the reply. Note that key will be evaluated as a regex, and special chars like . should be escaped if you actually mean a dot, eg: \.
Is already included, but can it also be added that the reply tags the @username.
The autoresponder replies to the specific post of the user, meaning they will get a reply notification, and it will also be recorded that the post replies to that specific post; just like this post shows that I replied to your post in particular:
Is there a particular reason you want to add an explicit @ mention to the user in the text, like @Festinger, in addition to all the above?
