Perhaps one of the best, if not the best free ajax powered shoutboxes out there, Planet MiniBox looks the part with it's streamlined CSS design and plays it well. The most exciting feature that sets MiniBox apart though is not it's excellent chat, but it's tabbed private messaging service. You can have a confidential chat with anyone online in the shoutbox at any time by simply clicking on that persons name. A mini-tab will appear in the shoutbox. Once clicked on, you and that person will be talking away from the prying eyes of others. Best of all, there's absolutely no limit to the number of people you can be privately talking to! MiniBoxes are ridiculously easy to put on your website. Simply copy and paste some code generated and off you go! Using a point-and-click interface you can easily re-skin your box to fit in with a new layout or design. Two version are available. The free version contains a link-back to Planet MiniBox (afterall, it's only fair!) whereas the premium version, costing $20 a year has no-link back, allows you to have pictures or images as backgrounds, avatars for users, register user option, moderation option, increased speed and a whole lot more. Generally, like all good things, if you pay, you'll find it's better. It still doesn't stop Planet MiniBox from being one of the best services around though!
