The only page which allow visitor to add comments is the About Planet Singapura page. This is where visitors can give comments and feedback regarding Planet Singapura, the aggregator site, itself. So far, nobody has added any comments yet. :)
To make it easier for visitors to send feedback about Planet Singapura, I have added a shoutbox, which you can find on the lower right sidebar of the site. The shoutbox is powered by Shoutmix. Feel free to give your suggestions, comments and feedback regarding Planet Singapura there.
