Hey there and thank you very much for this great plugin! I've tried out several plugins including premium plugins, but yours seems to work out far better than some 20$-plugins...
Nevertheless I have some questions left:
+ is it possible (and how) to create more than 1 plugin? I run a site where I could use several different plugins like one general newsletter opt-in, one for the product page and another one for exclusive entrance to the downloads
+ how can I customize the themes? I'd love to change the background colour of the themes, for example.
Our site is http://www.studienstrategie.de - I'd be glad to hear from you soon!
