[Plugin: Newsletter] Welcome Message

Hello,

Recently updated the newsletter plugin, and everything works well. However, on previous version, after the user signed up for the newsletter, the ‘welcome message’ would be displayed within the subscription box, not on its own page. Is there are a way to get it back to this??? Or, is there a way to put a ‘Back’ button on the new page, which will take the user to previous page?

Many thanks
