Hi,
Looks great. Considering buying tier 3. However, a review posed these somewhat caveats:
1. Requires an upgrade to change the logo colour.
2. Full-screen embed made it impossible to re-enter my site to edit (DNN platform). This forced me to restore a backup on the site!
3. No ability to remove the Powered by link. Having any links to outside websites (especially non-related content) should be my choice. It is an SEO issue. Displaying the link promotes flipbooklets and undermines my site's SEO.
Are you going to change these caveats?
