Hi @clampitt,
for the subscribe button, in Pro version you can create your own submit button designs and use that instead of the default button design that comes with the action box style.
but, you can also do the change via custom css (yes this works for lite version). paste the following code into the Custom CSS field – at the bottom of the action box edit screen:
.mabstyle-dark.magic-action-box form input[type="submit"]{ background: #0391B4; border-color: #02333F; text-shadow: -1px -1px 0 #06272C; }
.mabstyle-dark.magic-action-box form input[type="submit"]:hover, .mabstyle-dark.magic-action-box form input[type="submit"]:focus{ background: #14A2C5; border-color: #02333F; }
this will make your button color bluish. of course you can change the color values as you see fit.
as for #2 – removing “subscribe to…” I guess you copied the raw html code from your newsletter service? that’s where you should change/remove the text from. or go scan through the “Processed Form Code” and look for the text you want to remove. You should find something like this somewhere in the middle:
<label for="mce-EMAIL">Subscribe to our mailing list</label>
just delete that. or change the text.
