There is a message left to the new user through robots. However the information about the message on the talk page is not listed in the notifications? Why it is not displayed. I can see a greetings without any links.
@Dineshkumar - please confirm if I understood correctly the issue you filed:
On tawiki a new user
- receives a standard 'Welcome to Wikipedia!' notification. This notification is not a link to anything, which is also a slight problem if a user views this notification in a foreign wiki: the user cannot easily go to the wiki from which 'Welcome' notification came.
- User talk page is created automatically and some content is added
The last event - User talk page has automatically added content - does not trigger any notification.
The reason of not sending any additional notifications is that
- other wikis do not create a User talk page for a new user automatically
- a new content is not always added to new User talk pages
The issue will be priortized in our next Triage meeting.
