How to send your blog posts to YACS CMS ( yetanothercommunitysystem.com ) from posterous.com:
1) Find a section you want to be able to post to. You can only choose one section.
2) Note its number. You can find out the number easily, as it will be:
The ### – that is the number you want.
3) Edit http://yourwebsite.com/services/describe.php and change the BlogID
in the line for MetaWeblog to that ### number.
Example: If your section was 107 (http://yoursite.com/sections/view.php/107)
Instead of blogID=”” it’ll say “blogID=”107”
4) Now you can set up your YACS website to work with posterous.com!
( If this works, the resulting page also should show up on http://free.naplesplus.us/sections/view.php/107 which is a YACS website which will be proof that this works)
