Re-attempt to access postsecret.blogspot.com. If successful, find out how users can submit secrets, locate an 'About' section to understand the project's mission, and identify how to browse an archive of older secrets. If the site remains inaccessible, clearly state this.
Navigate to 'https://postsecret.blogspot.com'. If the page loads, look for a navigation menu, sidebar, or footer that contains links such as 'About', 'Submit', 'Archives', or 'Contact'. If an 'About' link is found, click it and summarize the project's mission. If a 'Submit' or 'How to Submit' link is found, click it and describe the process for submitting a secret. If an 'Archives' or similar link (e.g., by month, year, or category) is found, click it and describe how users can browse older secrets. If any of these sections are not explicitly linked, describe the most prominent navigation elements available on the page that might lead to such information. If 'https://postsecret.blogspot.com' remains inaccessible (e.g., due to timeout or error), explicitly state this.
The agent successfully navigates to 'https://postsecret.blogspot.com' OR explicitly states that the site is inaccessible. If accessible, the agent identifies and describes the method for submitting secrets (e.g., mailing a postcard, specific address). If accessible, the agent locates and summarizes the core mission or purpose of the PostSecret project as described in an 'About' section. If accessible, the agent describes how users can access or browse an archive of older secrets (e.g., monthly archives, labels/categories). If any of the requested information is not found on the accessible blogspot site, the agent explicitly states its absence and describes the navigation elements that were present.
