They don't have customer service, just a "help center" set up as a "leave your complaints in the box" design. They limit the number of characters a question can have *including spaces*, AND limit the *limit of characters (if you have 10 characters left, you can't post the question) . They won't notify answerer's if the inquirer has a question, instead, it's just a "comment" option: no reply (is that not intuitive?). It hurts to see such a great platform have so many stupid rules which no one is willing to change.
Please try to spread this to people who can make a change if you agree. This is about the pursuit of knowledge, and confronting companies that refuse to change for the better of the customer.
