There's a few errors listed in Elgg documentation that the community needs to be aware of. In order to expose this to the developers, I opt that there should be a shared page for documentation errors.

Here we go:

http://docs.elgg.org/wiki/Views/Page_structure_best_practice

• It says: You can then, ultimately, pass this into the page_draw function: echo page_draw($title, $canvas_area);
• echo is incorrect since page_draw already echo's.

Cash's comment: Thanks! This has been fixed in the wiki. Keep them coming!
