Maybe I'm on the wrong track. I cannot see my new doc type.

First, let's see if I'm going about it right. I want to display a list of speakers for an event. The Kentico Author should be able to add or subtract speakers as needed. Speakers should flow onto the page three-abreast, then wrap to next line, like this:

Speaker1pic      Speaker2pic     Speaker3pic
title1        title2        title3
blah blah     blah blah     blah blah    

                        Speaker4pic
              title4
              blah blah 

I figure what I should do is
1] Switch to Site Manager/Development/Document Types and create a New Document Type called "Speaker", to which I add a speaker's info fields.
2] add 4 documents of type Speaker to my "Events" page, filling in the forms with the data for each speaker (pic, name, title, blurb, link).
3] drop a repeater on my page, that will pick up doc type Speaker.
4] write a transform to take the data and display it, one div per speaker
5] put the repeater inside a container div with a fixed width, forcing the speaker divs to wrap after 3 speakers

Assuming this is a good way to do it, I'm stumped between step 1 and 2. I created a new doc type with a bunch of fields I want per speaker, but the doc type does not show up in the results when I try to "New... Create New Document" within my Events page of the Content Management tree.

I thought I'd done it right based on the tutorial but no. Does it have something to do with improperly specifying Document type display name or Document type code name within the Document Properties when creating the new doc type?
