Hi,
I guess you want to add video in the 4 content boxes? That’s not possible cause it only can contain text.
Few months ago I created a static homepage template. Only difference with default SimpleCorp homepage is I removed the 4 contentboxes. You can add text, iframe, image, because it’s a normal page now:
http://www.webmastergroningen.nl/homepage.zip
(contains 2 files: homepage template (create (home)page and select my template on the right) and example text for creating 4 look-a-like contentboxes)
The + is an image and located in css stylesheet:
.readmore a {background: url("../images/blog-permalink.png") left bottom no-repeat;}
