hidden markup in twiki pages

[Ray Plante]

Hi fellow IVOAers,

FYI, I've noticed on two occasions now in which hidden text that is
obviously unrelated to IVOA activity has been inserted into IVOA twiki
pages.  (The text is hidden by surrounding it in tags with style="display:
none;".)  As the text tends to contain links, I suspect the motivation is
to influence the rankings and the like calculated by search engines.  In 
both cases the text appeared either at the start or the end of the 
document.  

I would recommend that if you, while editing a page, notice such text to 
go ahead and just remove it.  

cheers,
Ray
