I have put up the Firefox Extension for coComment! I and a few friends have been using it for a day now and it seems to work fine!
Laurent has posted a few coComment invitation codes in my previous post's comments. Thanks, Laurent. Make sure you get them before they are gone.
SolutionWatch has put up a quick review of coComment with a Greasemonkey script
Also, here is the screenshot of my Firefox Extension for coComment that allows you to coComment! from the right-click context menu that I quickly put together. This extension is of a great help especially when commenting in pop-up windows where you can't access your bookmarks. And even on a general page, reduces your onscreen movement time (Read more here).
Its high time I got myself some web hosting space.
