This version is incompatible with the 6.14 version of Drupal core.

variable_get('annotate_node_types', array('page'))
Default value shown is not consistent with the module's (see last line on page 19).

We're going to allow annotation of page node types by default
The code example on p 17 and the screenshot on p 19 show 'page' as the default; the one-line code example should reference 'page' too instead of 'story'.

'annotate_node_types'
Variable is given a different name than in previous and following examples.

if (!in_array($node->type, $types_to_annotate, TRUE)) {
Also on page 26, middle of page.
Strict mode for in_array() must be used or the if will fail and thus the annotation form would be displayed on nodes of all types, not just the types selected in Home / Administer / Node annotation. [Fixed in downloadable code.]

CREATE TABLE annotations (
uid int(11) NOT NULL,

created int(11) NOT NULL default 0,
PRIMARY KEY (uid, nid)
)
I know that the SQL is "something like" - but - having pasted it in and used schema module to cut'n'paste the code it would be better if it actually was valid SQL and matched the schema that was used.
There are two points that don't match
1) table name ("annotate" vs. "annotations")
2) column "when" is really column "created" (and "when" is a MySQL reserved word so would need quoting)
Plus - one error (at least for MySQL) - an extra comma after the PRIMARY KEY column.

Sun, 09/07/2008 - 11:32pm — mikewhobikesIn the downloadable code, hook_install() is missing the line to delete the module's variable.
Update online code to include:
variable_del('annotate_node_types')
Omission from online code.
[Fixed in downloadable code. -JV]

In Drupal 6, clearing the menu cache is no longer enough. You must rebuild the menu_router table to get new menu entries to appear. The menu_router table is rebuilt automatically when you visit admin/build/modules, or use the devel module to rebuild it.
