^ so, you'd risk using a vulnerable script just because it's seo'd already.
and tbh. seo'ing WCDDL is fairly easy... you just need to change the url paths (simple html changes) and use a few htaccess rewrites. also use <h1> <h2> <h3> tags and some other simple seo work.
edit: If you would still prefer DDLCMS, I think DDLCMS v3 will be released soon, so you should watch out for that.
