The above link to an "installation tutorial with screenshots" isn't available anymore....HOWEVER...it can be now found at... http://www.howtotuts.com/2008/01/12/how-to-start-your-own-job-site-with-jobberbase/#more-5
(Not sure how up to date it is) but I'll try to follow it when installing Jobberbase this weekend. I'll keep the screenshots along the way, and IF (notice the big 'IF') all goes well with the installation, I'll post the screenshots.
