hi,
i posted this below but its about to fall off the board so here it is again... Annie Duke wrote some good O8 articles for
www.ultimatebet.com
this is how you get there: go to the website as mentioned above (NOT the software start page) and click on Team Ultimatebet; then click on the name Annie Duke on the right column; then click on 'Learn Omaha from a Pro' in the right hand column which will take you to the first article and at the bottom of that page are links to further articles.
This is the link to Annie's page, not sure if it'll work:

good luck
Daisy
