I've wirtten a (tiny) patch for Tiki Blogs that
provides an "extended text" feature.
"Extended text" means that a blog post can have a small
section of text shown on the blog page, yet have the
full text on the "perma link" page. This works with
single and multipage posts.
This patch brings Tiki blogs into line with products
such as GreyMatter, Blogger, MovableType etc, which do
not require all of a post to be on the front page of a
blog. They (in the main) do not support multi-page
posts, mind you ;-)
I'll put a bit more info on my userpage on Tikiwiki.org
and you can also get me at http://www.coofercat.com/.
