Hm, unfortunately it isn't possible to render quick registrations on 3rd party modules but if you use the login box module provided by us, it does render quick registrations

Hey Mark,

what i mean is, to include it with loadmodule or loadposition in a article/modu with custom content on a landingpage.

Yes, it should work as long as you configure correctly the loadmodule/loadpositon in custom HTML module.
