-Yes, in current format, the FlashBar is just a concept. You cannot see or play with it just yet. The idea behind it though is an interface [sort of like a menu] that you can navigate through and select one of several different games [and potentially other things like notes for your blog or whatever], all in an extremely tiny 350x19 footprint. These dimensions are identical to the Userbar spec, so it will integrate seamlessly with them.

-I guess whoever asks this question doesn't understand the concept of a Userbar. The Userbar design process is to create a picture showcasing something about you that you put in a forum signature. At first people used a bunch of individual pictures, with quotes like "Gamecube Player" and "Spam Eater", but they are now moving towards animated ones that display all of them in a single 350x19 footprint. The FlashBar is supposed to integrate within several userbars, directly next to a single animated userbar, or replacing all of the userbars together!

-Simple. HTML enabled forums. Here are the steps to properly nest them in your sig:

1. Ensure the intended forum allows HTML, specifically the <embed> tag, in the signature area of your posts.
2. Start to edit your signature.
3. Find the point at which you'd like to embed the Flashbar, and use the following embed tag: <embed src="url://url.url.url/url.swf" quality="high" bgcolor="#ffffff" width="350" height="19" name="flashbar" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
4. Replace "url://url.url.url/url.swf" with a good flashbar url, ensuring that it has the swf extension.
5. Save your sig, go post something [ensuring that you're showing your sig in the post], and make sure it works.

-You really should discuss enabeling an tag over with whoever administrates your forum. I am certain that with a little work, any admin could set up a small whitelist for <embed>ded content.

-I would eventually like the FlashBar to be a gateway to any content you need. I don't intend to replace the browsing experience, but it could really be useful if people designed content oriented for it. I'd love to see new innovative ways to use such a small space! Another goal is to be able to dynamically resize/close/open/etc the FlashBar. At first I think we'll just keep it to increments of 350x19 though [350(x)x19(y); x={1,2}, y={1,2,3,4...}].
