the topic might be a little off, but I'll explain.

So, I've written a project in latex for a Linux conference. It currently contains only the text that will go to sponsors and local media. It contains the plan of the conference without the realization details.
Now I'm going to add technical details and duties for every chapter.
For example:
(original text) This is going to be a cool conference.
(organization comment) Mark: Gather the "components of coolness" till 2.3.2012.
What I would like to achieve, but don't know how is to have all the written comments gathered on a last page of the documents (together with the ones in chapters).
In the ideal solution, they would be sorted by names.
Any ideas?
