I think this is fine. But isn’t he supposed to announce what the new protocol will be this week? And it’s expected to be contingent upon hitting a certain vaccination rate, right? You might just wait to see what is announced first so you’re not constantly updating your website.
For the live cast, would recommend you release the info ahead of the wedding date, if at all possible, to let people test out the website (make sure they have the right software updates and all that) so they don’t miss a moment of your ceremony.
My venue is already at a enough people to host my guest list! I downsized months ago to avoid any last minute "un-invitations." I feel comfortable posting it now since we're stable! The wedding is June 13th and my invitations went out on Friday, so I really wanted it to be there when people visit the website.
