WPf2b v4.3 now fully supports multisite networks in both the Free and Premium versions.

The biggest change is that WPf2b is now a "network-only" plugin; in other words, it can only be activated at the network level. Previously you could activate WPf2b for individual sites, which frankly made no sense at all.

For the Free version this has no effect beyond individual site admins no longer being able to see the WPf2b settings, but for the Premium version there are two important changes:

1. it requires at least a Silver license,
2. it requires only one license for the whole network

If you're an existing Bronze user with a network, contact me and I'll bump you to Silver for the year.
