So the first few issues are flowing in... the package on wordpress.org didn't work... I developed the plugin in a folder called lnx_lifestream but wordpress.org's fancy system changed the path to linickx-lifestream - DOH!
There was also an FAQ missing from the readme.txt, ie how to resolve the error message...
Can't find Wordpress, edit \$WPDIR in run.php
This has now been fixed (link to faq)) but does shed light on a new issue... any changes to run.php get over-written on upgrades, I will need to think of a new plan to overcome this!
