I came across a post today at Fairy Tail Treasures. That link goes right to the post. The post peaked my interest so I clicked on a link at the bottom to their site. Now I had to know more! Their blog The Life of an Unbalanced Libra really grabbed my attention! No 'hard selling' ANYTHING, no guru know it all arrogance, just sounded like an honest, no alterior motive author! So I did what the blog said I needed to in order to join (simply send an email request). I also had a question about the blog so I added that to the email as well.
A very short while later I had a response from them! From a REAL person! What a pleasant suprise!!! 
For 'joining' this site I got three pdfs (two about GPT sites that I had joined at their suggestion and one about who they are and what they do), access to their members only section , and an invitation to their forum. The cost? An email address! 
I emailed the site owner back & forth a few times for clarification or with questions. Ms Lisa was extremely friendly and professional!
If you are thinking about trying a GPT venture or if you are already doing some drop by and take a look around at Ms Lisa's blog! You'll be glad you did! Oh, and btw, those links are direct links! No affiliate nothin' there! She's good people!
