[Evolution] My second attempt to migrate to Discourse failed, too - Aka Re: My first attempt to migrate to Discourse

[Ralf Mardorf <silver bullet zoho com>]

20. "Welcome back!
     Incorrect username, email or password"...
21. ...but "with GitHub" I can log in again.
22. Puzzle piece/space invaders icon > Bust icon > Preferences
23. Added alternate email silver.bullet at zoho...
24. Evolution retrieved emails
25. Ralf clicked confirmation link
26. This was wrong, hence I clicked "Preferences" again
27. I clicked the wrench icon
28. I clicked change email
29. Cahnged to silver.bullet at zoho...
30. Evolution retrieved emails
31. Ralf clicked the new confirmation link Nr. 1
32. "Sorry, this confirmation link is no longer valid. Perhaps your
    email was already changed?"
33. Ralf clicked the new confirmation link Nr. 2 (yes, I got two of them
    this time)
34. "Please confirm you would like to add an alternate email address:
    silver.bullet at zoho... [done]

Incidental remark
    From time to time it's a good idea to close one or the other tab
   opened by the confirmation links.

35. I clicked "Preferences" again
36. I clicked "Notifications" (just related to the forums)
37. I clicked "Tags"
38. Select
    gtk, glib, python, vala, rust nothing else, excepted of "Muted", it
    shows "evolution"

Sorry, I'm too stupid! How can I enable mailing list behaviour. Please
provide a step by step guide.

Regards,
Ralf
