Another SSL Request - https://www.startssl.com

It would be great if there could be support for STARTSSL they provide free and payed (finally some normal prices) SSL certificates...

Sure this request can be considered, Put request to StartSSL that contact HC team in sales at hostingcontroller.com and discuss about integration pre-requisites.

I have put out an email to startcom about the suggestion but due to tight security around the system of startssl it's not possible to integrate.
 
So what's possible is a link to the sign up form, that would be something we as host could build in by some extra custom menu so people know it's out there.

You can add a custom menu in hosting controller which will be visible to resellers/webadmin.
Login in HC as host then go to location " My Server :: Custom Menu "
