Are the venues Hot Reads and Galleries different categories within Connections or are they two different network site? I can not really tell, but I’m guessing two different network sites. If that is the case, it depends on how Connections is setup. By default on a multi site install of WP, Connections will run in multi site mode, meaning each instance where Connections is activated on a network site is isolated from each other (does not share data). However, Connections can be configured to run in single site mode on a multisite install of WP. This mean in each instance where Connections is activated on a network site it will share the same data across all network sites. Is the latter what you want?
