looking for "News banner" plugin

[monger_39]

Hi all, 

I am looking for a plugin that would allow me to add a simple 'News banner' on the Jenkins home page.

This is to announce upcoming maintenance, new items or other.

Not much fancy stuff is needed: all I would want is a piece of text with minor formatting.

After searching, the only plugin that I could find is the 'Page Markup', but afaict that is meant to add a 

more permanent 'branding' banner. That is not what I need.

Any advise ?

thx, M
