3. Sekarang tinggal simpan perubahan dan selesai.

Catatan:

• Untuk mengubah jumlah daftar komentator yang ditampilkan di blog, cari var maxTopCommenters = 8, dan ubah 8 dengan jumlah yang sahabat inginkan.
• Untuk mengubah ukuran avatar dari komentator, mencari var sizeAvatar = 33, dan mengganti nomor 33 dengan jumlah piksel yang sahabat inginkan.

Semoga bermanfaat.
