Assessibility
Every step in the design of Contentor was was made with accessibility in mind. Sites created with Contentor should be accessible, as long as the template itself is kept accessible.
Making your site accessible
The first step to making your web site accessible is to firmly set your primary goal (i.e. to get INFORMATION to your constituency) and then, make certain that your secondary goals (i.e. to impress potential funders with what a clever web designer you are) do NOT imped on your primary goal.
If this the previous sentence causes any arguement or adverse reaction with you, don't waste your time reading further. I don't have time to have "that" arguement again. A blank web page starts with lowest number of barriers to accessibility - the designer must avoid adding anything to that page that increases those barriers.
It takes only a small bit of time to identify the barriers to acessibility.... http://bobby.watchfire.com/
Flashy web site features which impresses for a moment could be a permanent barrier to a person with a disability.
Separating Content and Presentation
Since a Content Management System is intended to simply content management (duh!), it is best to keep the cont as free as possible from embedded formatting commnads. Pasting in html 'font' tags may make the page immediately more 'pleasing', but in the long run, makes the site appear scattered and frustrates any attempt to change the look of the site later.
Descriptions on your images
When you insert an image with the image selection form, there is an entry label "Description:" that results in an 'alt' attribute added to the HTML image tag. This has several purposes, including describing the image via a screen reader, explaining the image on a text-only browser (think PDA or cell phone) and also makes the image easier to find via a search engine (e.g. Google Image Search).
Putting a descriptive 'alt' attribute on your images is the single most important step to making your pages accessible to averyone!!
