Dear all, Some weeks ago I ask at http://drupal.org/node/20577 about OG and TA compatibility and Moshe answered that they are not, to say the least, very compatible ! Some weeks later, Robb came and made a new module which enable many modules using node_access API to work together. It can be find here http://drupal.org/node/24868 (but the latest beta should be currently request from Robb). As I am far from a developer, I can't say anything about the way he has taken to achieve his way, but as a user, I can say that this is a great improvement as I can now run both OG and TA. In his latest today email Robb said "Response to the module has been minimal and I am moving away from Drupal [...]". He has done a very great job on this issue and I think many others could find his module very valuable. So this is my "SOS" to you guys, hoping it could find a way and Robb work won't be lost for future Drupal developement. Regards, Eric
