If you are interested in databases, have questions, or wish to contribute to the discussions you'll be welcome as a member of DBForums. If you'd like to advertise your services here, I can put you in touche with folks that can help you to create and place an ad campaign.
If your only reason for posting here at DBForums is to advertise, CMS really doesn't have anything to do with DBForums. A CMS system uses a database, but CMS isn't a tool to use, manage, or monitor a database so it isn't really appropriate to advertise or evangalize your services here.
If you're looking for a site where you can participate in CMS discussions, you'll do a lot better at a site like http://www.webhostingtalk.com/ where discussing and advertising a CMS service would be appropriate.
In theory, theory and practice are identical. In practice, theory and practice are unrelated.
