Sorry Guys, I didn't get much farther in correcting some of the issues raised. Originally I was working on the flyout and could get the flyout larger, but could not get it to list more users and I'm pretty sure its not up to the gadget as to how many users get listed. If you take a look at this link, you'll see the same as the flyout and all the flyout does is display whats provided from this address, so it up to "others" to set the amount of users displayed and how often it's refreshed.
Flyout address:
http://www.kcs.gr/gadgets/a.php
Along with that address, is the main window, threads website. Looks like much to do with it is also not under the control of the gadget, but from this site and/or from hosting site,...dunno, I just don't enough about coding, thought I could get at the very least the user avatar, but I can't even find any reference to it in the gadget.
Main Gadget UI: (you might have to log into the gadget with your username and pw to see the threads displayed in your browser). If your already logged into the site and/or the gadget, you might just be able to click login without inputing any info, if not just log into the gadget as you normaly would (same as your sevenforums username & PW).

Edit/Added:
Also with seeing the "Warnings" at the top of these web pages, that means there out of the control and not part of the gadget as using these links, completely bypasses the gadget as the gadget only displays whats provided to it.
Not sure, but maybe its because of IE8 changes from previous versions and its compatibility mode? If anyone has IE6-7 and the gadget, ...they might not be seeing the Warnings, ...just a guess though.
If you wish to use IE instead of the gadget, you can resize the window (less than 100%) to remove the overlay, otherwise it works just like the gadget. If I have my IE8 window open full and change the zoom to 84% (Custom option at lower right) I have no overlay.
Hint: With IE8, when you want to open a thread from the gadget webpage press and hold the <CTRL> Key, while clicking on the thread link. This will open the thread in a new tab. This also works for all other links including Favorites, and links from other web pages.
