Submitting templates to template galleries is a good way to ramp up traffic. Thousands of designers download templates, whether it be psd or psd +html with CSS. Instead of having work sitting around we can encash it.
http://www.freecsstemplates.org/ a not so great site has a PR of 8. That's awesome and I have taken a few of their templates and considered using the companies listed. This will help us build our profile and generate leads.
It is a good idea to have our own interface to which will allow users to showcase their work, and for people to review and rate them. This will generate much more traffic over time. Premium templates can then be sold off this site.
Looking forward to have a look at the template site mentioned.
