I wouldn't call this a good news. I've been using their free certs for a while. Oh I can't get the Thawte link to work
but I trust the source. Remain Comodo free certs, but there's no possible management of them like with Thawte; there's also sofware to generate your own self-signed (so not trusted obviously, but no big deal), but I never tried. Thawte was a perfect solution.
I'll login to their site and see if I can find anything...
