Have a website redirecting to the openvsx with the theia name in it.

Feature Description:

It is hard for newcomers to know where to browse for plug-ins.
Open-VSX.org does not mention Theia at all. So when companies evaluate ecosystems, Theia does not look as good as it is.
It would be good to have a site like www.theia-extensions.org or theia-vsx.org that re-directs to http://www.open-vsx.org.
