With Gabbly you can add live chat to your Wikispaces wiki. Now the readers of your Wikispaces wiki will be able to chat with each other using Gabbly right from your Wikispaces wiki.
Go to Gabbly. Gabbly is a chat board that you can add right into your Web site, wiki or blog. As long as your server allows you to add code to your site you can probably add Gabbly.
