You can check your mail, the mail indirectly tells you about your credit points. And I don't think there is any another way to check. You only get notified about the points earned by publishing a trip. So, just check your mail and guess where this ponts came from.
Post trip and photoblog and Tripoto will analyse importance of your post, grammar and count of views and wishlist and they will allocate credit points as per above points. After 48 hours your credit points will reflect in your account. For further information follow me and text me
