[Plugin: SexyBookmarks | email, bookmark, share buttons] Google 1 Link change

Hi All.

need help with G+ Link change.
I have 2 G+ Pages at my Account on Google.

Second page created as Advertise page and I would like to
send a WP Contest to second page. As default I couldn’t because
G+ every time goes to the First page.

I would like change G+ link directly to second G+Page.
Anybody can help please?

Many thanks in advance
