If you publish your site to MobileMe, you can let visitors add comments and attach files (which other visitors can download) to blog, podcast, and photos pages. These comments and attachments are visible to anyone who visits your website. To prevent automated programs from posting spam to your site, anyone who posts a comment is first required to type a displayed group of characters.
Comments appear as soon as they’re posted, and you can delete a comment and its attachment at any time using iWeb or by visiting your site with any browser. You can also turn off comments to prevent new postings without affecting the comments already posted.
Comments and attachments are stored on your iDisk. Each comment can be a maximum of 32 kilobytes (KB), and each attachment can be up to 5 megabytes (MB).
Important:Before posting anything to your website, make sure you own the copyright and other rights to what you or others are posting, or that you obtained all necessary permissions.
