I think its already been 3 weeks since the proposal has reached 100% commitment. So, When are we going to have our Hinduism community.
Barring any unforeseen technical delays, Hinduism SE is slated to launch in the afternoon (Eastern Time) of Wed, June 18th.
To quote from the banner displayed at the top of the proposal page:
Site launches are currently on hold due to a problem with Google's OpenID service, but should resume next week (16 Jun)
That said, Craft CMS launched today (June 12 UTC), so... I don't really know what's up.
