Since the release of the Plugin a few months ago, I've made a number of small changes to make it more friendly. The most important is also the most recent: adding WP-Cron support.
A cron job is a scheduled, repeating, task that runs on a server, usually used for automation of tasks. WordPress has the WP-Cron category of functions that offer similar functionality, but with one important difference: the jobs are triggered by visits to your WordPress site (or Dashboard).
In the case of this plugin this means that whenever someone visits your site, all contacts added by Gravity Forms between this visit and the last visit are sent to Solve360.
A full list of changes made to the plugin is available in the Changelog.
