Yes, this is something not usual, however this can increase your site visitors and this will be a new good back-link to your site for Google PageRank.
I found a good suggestion in the CMSFeedback Community. They ask webmasters to create a new topic in according CMS subforum with your site URL and list of plugins you’ve used. So peaple will be able to see alive example of site made on that CMS. They’ll discuss about your site functions and features, as a lot of questions about your site and visit to your site. I think such a discussions may be very useful for your website.
The registration is very easy, just username, email and password.
Then find the according subforum ( for your forum software ) and create a new topic with this template:
Topic title should be: SITE: Your Site Title
Topic Body text template:
[b]Site URL:[/b] [url]http://example.com[/url]
[b]Based on:[/b] CMS Name
[b]Installed plugins:[/b]
[list]
[li]Plugin Name 1[/li]
[li]Plugin Name 2[/li]
[li]…[/li]
[/list]
[b]Installed theme:[/b] Theme name
[b]Description:[/b] Summary about your site…
