mkiisoft on "[Plugin: Jetpack] Publicize URL & Content problems/customs"

Hello guys!

I have some issues with the Publicize in Jetpack in my social networks.

First, In Facebook always post "WORDPRESS" at the bottom of the image and not my site URL "RENDERASNEWS.COM". Is it any way to change this? It also post an small image and not the entire frame of the post in Facebook.

Second, the post in Facebook and Google+ use almost the ENTIRE content of the post. Like: "bla bla bla bla bla [ 189 more words. ]" and it looks terrible... Is it any way to just post a summary (like 10 words of something) or the title?!

Thanks in advance!
