I've tried to apply a patch for MDL-13835 to hide the courses someone is enrolled in from other students who have no need to access that information. In testing this, it seems there's not any type of check for when the payment button appears. The payment button appears when you click on another student's profile and while their payments don't appear it would seem there's no need for the payment button to appear at all when clicking on another students profile. I'm also including a link to the forum discussion on this topic. http://moodle.org/mod/forum/discuss.php?d=97747#p441442 Here's an update from my original post. I obviously didn't understand the default behavior, but I still think this might need to be addressed. After testing some more in the default install, when clicking on another students profile the payments button seems to reflect the payments of the student who is logged in, not the student whose profile is being clicked on. I didn't catch it before because I typically use the same test amounts when I run payments through under my own name using different user accounts and the one account I hadn't run a payment through yet. I just looked at my 1.6 install and it works exactly the same way. I've never noticed it before because I've never had the ability to change/add user profile fields. I think if someone uses the original patch from Mike it will do exactly what was intended and that's hide the courses enrolled in from other students. I still don't think the payments button is necessary when looking at someone else's profile and there's no reason for it to appear because it's somewhat of a mixed message. The messages button applies to the student profile your looking at and the payments button right next to it applies to the student logged in, but it appears that's the default behavior. Todd
