Append node to forms
Formnode is a simple module that allow site administrators to render nodes into forms as HTML markup. You can select a node, the form where to render the node, and the weight to position the renderered node wherever you want.
Note: this module is not maintained anymore, and won't be in the future.
A D6 version will appear shortly, we needed it for specific projects.
It provide a simple and intuitive UI, using form_collect and form_store modules if they are enabled on the site. Else it provide an old and unusable UI :) Those last two modules can be disabled after site configuration is done.
