I'm new to Threads (6.2) and still learning, so forgive me if this is dumb question. But I've noticed the threadsdev home page, along with other such as dalantech for example, have their home/index page made up of threads components. Is this an option in the system or is it the fruit of creative webmasters?

Either way, it's a nice look. It allows you to introduce your site and have the forum right in front of the user without them having to click through to get there.
Thanks in advance.

They all use the excellent add-on IIP by JustDave, you can find the latest version in this thread.
