 ## Mastodon Configuration
 
-After logging in, open <http://localhost:8000/profile>, enter the Mastodon instance, and select **Connect Mastodon**. LinkLog registers an OAuth application on that instance, opens Mastodon authorization, and stores the returned per-user access token after the callback. The requested scopes are `read:accounts` and `write:statuses`.
+After logging in, open <http://localhost:8000/profile>, enter the Mastodon instance, and select **Connect Mastodon**. LinkLog registers an OAuth application on that instance, opens Mastodon authorization, and stores the returned per-user access token after the callback. The requested scopes are `read:accounts` and `write:statuses`. Posts use the configured prefix followed directly by the title, an optional comment, a `from: URL` line when a title exists, and tags on the final line, with blank lines between sections.
 
 - **Instance**: hostname or URL such as `mastodon.social` or `https://mastodon.social`
 - **Post prefix**: text placed immediately before the link; defaults to `From my #LinkLog: `

 ### Assistant outcome
 Removed the duplicate `TRAEFIK_HOST` configuration, changed both Traefik router rules to use `LINKLOG_PUBLIC_URL`, standardized the value as a host name, and normalized scheme-less values to valid HTTP/HTTPS backend callback URLs. Compose validation, URL normalization, and the complete Dockerized backend suite passed with 22 tests.

+### User
+Format Mastodon posts as `From my #LinkLog:`, the web page title, an optional comment, and `from: URL`.
+
+### Assistant outcome
+Updated the Mastodon formatter to emit the configured prefix, title, optional comment, and source URL as blank-line-separated blocks. Tags remain on the source URL line. The focused posting test and complete Dockerized backend suite passed with 22 tests, and the running container is healthy on port 5469.

+### User
+Only print the `from` line if there is no title. Put the title directly behind the colon, and put all tags on the last line.
+
+### Assistant outcome
+Updated Mastodon formatting to place the title directly after `From my #LinkLog:`, omit the `from:` line when no title is available, and place tags on a separate final line. Added no-title regression coverage. The focused tests passed and the complete Dockerized backend suite passed with 23 tests.
