We definitely need this! It's very painful as a user to always go to the English community.
I also hear a lot of customers in Germany say "It's so sad that they deleted the Gallery without any replacement, there were so many useful macros". They are always surprised when I show them that some of the content it present in the new Gallery.
Just to clarify here - are we just looking for a link to the main Gallery from the international communities? That should be fairly straightforward, but creating separate instances would require much more effort on the platform team.
