Hi Themeco,
Try the email forms extension, http://demo.theme.co/email-forms/
On version 2.0.3 in the current TF cdownload when I create any form of any style it seems to generate 2 extra
<fieldset>
</fieldset>
<fieldset>
</fieldset>
Tags inbetween the email input and submit button. Not really a problem, only that these extra tags create a space between the email input and submit when display: inline; is set.
This behaviour is not the Themeco demo, however I have installed it multiple times on a number of clean installs, including, excluding names, combing names, etc. and the same happens every time. Is the version in TF the latest, does the same occur on your test installs?
