Suggestion: ALL ACTION BUTTONS SHOULD BE MADE MORE VISIBLE.
"ACTION" buttons (examples are Register, Next) are not emphasized enough (perhaps a larger size text, or bold text, or a box put around the text, etc). This lack of visibility is causing confusion among infrequent users who miss what to do next in whatever process they are going through. The result is that, I the administrator, have to spend time and effort processing and helping users who have failed to complete a process (eg payment). I look forward to your comments
