Agaric wants:

agaric: We have some users who would like to expand and collapse comments with ajaxy little plus and minus signs rather than the default all or nothing comment option.
[8:02pm] agaric: Is there a module, or theme snippet, or generally known solution hiding itself from my searching skills?

drupal collapsed comments
drupal theme collapsed read comments

thanks to Gurpartap on #drupal-support:

Questions you'd want answered desperately fast if you did something remarkably stupid such as putting invalid PHP code in a block that breaks your entire site, even if you were lucky – I mean foresightful – enough to limit that darned block to a single node.

where is custom block text stored in drupal database
where is block data stored in drupal database

How to make a business model out of doing the right thing?

Make open source software that tons of people use for free.

Write a book documenting it that people do pay for.

... and then wikify the documentation:

The simplest hacky thing worked-- adding a space in front of the title.

Agaric would like breadcrumbs in Drupal to just work, but barring that until book navigation becomes general navigation in Drupal 6, we'd just like control...

Custom Breadcrumbs module

From the PHP snippet section...

Breadcrumbs including title

After some half-hearted searching...

drupal taxonomy nodes
drupal associate a taxonomy with a node
drupal link taxonomy to a node

Agaric thinks this can be done most easily with a taxonomy view.

You can create an author profile type that can be linked to a user account with usernode and nodeprofile and the like if you want, and limited to one per user.

Or just use a CCK type for author.

In either case, require that these be tagged with the author vocabulary.

and also to show that there really IS a collective...

This provides a pretty good technique to give people a link to their special profile node, to either add a new one or edit an existing one.

In this case, I set up a profile node type available only to one role, judge.

The setup that allows this follows the directions for using usernode, nodefamily, and nodeprofile to allow each user to have only one of a content type.

I created a block "Judge Profile Edit Link" and gave it no title.

Put this in it:

We at Agaric consider nonprofit organizations to be one of our core constituencies, although a majority of our work is probably for groups without official 501c3 nonprofit status, for businesses, and for individuals. We try to stay in tune with the needs of organizations for good, whatever their tax filing status.

svn commit -m "replaced nodefamily-5.x-1.1 with nodefamily-5.x-1.2, a module upgrade. Since our module setup has module upgrades going into a wholly new directory, it may be particularly importont to 'Submit' the modules page after upgrading... as well as running update.php of course. It's also very important of course to delete the older version of the module, since the names won't conflict and remind you."

UPDATE: running update.php seems to find the upgraded module quite well.
