In 2009 an editor added an "Ohloh" badge as screenshot, mentioning in the edit history, that the JavaScript to embed the badge isn't allowed on Wikia pages (or actually on any MediaWiki, unless the owner enables raw HTML or similar, unsuited for public editing.) Therefore I considered that remark as an "of course", and updated the image with a recent "OpenHUB" screenshot.
Some days later I wonder if there's a better solution, e.g., add the script to the System messages with admin rights, and use the system message to render the badge instead of a stale screenshot. In essence the same idea as for the RSS feature. Is that already possible (= can admins create new system message instead of only modify existing messages), and could it work for this purpose?
