I have spent a few hours searching the net for an answer to this. The examples I have found do not work other than to change the color of the form. Could you simply please just supply us the CSS that will put the subscribe form on 1 line? It would be nice to do that and possibly gain a customer instead of telling us to go read a page that is of no help. That reflects poorly upon your support! I don’t have the time to PLAY with it. Time is money and if you waste my time, then there’s no money for YOU!
It makes better sense that the add-on should have this feature built in since the majority of people who want to have a simple Subscribe on their main page simply want a one line form for this instead of a huge 2 line one.
So please for your customers and future customers, show us how to do it on 1 line.
