Elgg plugin needed to insert script code and iframe blog.

For Elgg plugin needed to insert script code and iframe blog.
This provides control over advertising on the site.
Problem to do it without disconnecting htmlawed.
Maybe do a blog form script, which will be open for admin. If they are separated from the content, htmlawed will not filter this code.
Form, you can assign the appropriate guid blog?
Ect option to modify the plugin unfiltered_admin (Matt) content filtered on output.
