Hi!
I tested your open atrium distribution - and I am really impressed. working with implementing and researching implementation of requirements seems easier with this intranet /kms tool.
Great!

I had to patch views to add a php version workaround with passing array where reference is expected. ( see here: http://drupal.org/node/569724 ) But there is one more issue currently -

"user warning: Duplicate entry '5' for key 'PRIMARY' query: INSERT INTO node_history(uid, nid) VALUES(5, 3) in /data/web/sites/nodestream/openatrium/kmdistro/sites/all/modules/features/bookmark_trail/node_history/node_history.module on line 134."

Do you have any tips for me on how to repair?

Cheers,
and thanks for great features!
