NextScripts: SNAP Pro

I upgraded the free version of Nextscripts to enable me to autopost to Googleplus communities. To be clear these communities were not created by me but I would like to autopost links to my website articles to them.

I’ve failed to do so and I think the reason is that the Nextscript plugin only enables you to autopost to Googleplus communities you yourself have created.

Does anyone know any different or does anyone know of a plugin that will enable me to post my website post links to Googleplus communities NOT created by me?

Thanks

Derek
