Try this.The ghettoest
Try replying to the first post...
When you click reply it will insert that first post into your message but don't do anything... I mean don't hit post or don't type a reply.
While that first post is sitting in the reply box highlight the Google sheet link then right click and copy it then close your browser or open a new tab and paste that link into your browser.
CrUd does this make sense to anyone or do I need to try and say it in a different way?
