The Gravity Forms plugin doesn’t seem to be active yet. Please activate it now.”

Only active survey plugin is “WP Survey And Quiz Tool” have previous deactivated “Polldaddy Polls & Ratings” in plugin list.

For now the plugin is AWESOME, but how can you make it to show all the time, not just once? Thanks in advance ^^
