If your current host is jacking your rates, it will destroy Godaddy imho

You might check out this group on BuddyPress hosting: https://buddypress.org/community/groups/buddypress-hosting/forum/ It could still use more people participating and sharing their reviews, but it’s a place to start.

The good thing is that you’re site is growing. The bad thing is that as it grows it costs more to host!
