How to check if a user has privs to access a node in organic groups Does someone know what function within Organic Groups I can use to check if a user (the signed in user) as access to a given node? Do you have an example? 

Thanks
The same function you should always use in any context: node_access('view', $node);

Modules are expected to use node access hooks to implement access control, so this function will consider all of the modules that may grant or remove access to the given $node object.
