After logging in, you can easily update your profile information through the "Settings" link in the dashboard. This section allows you to manage all the personal details associated with your account. When uploading a profile picture, make sure the image dimensions are 256 x 256 pixels and the file format is JPG, as images that do not meet these requirements will not upload. If you need to make changes to other profile details, such as your nickname or salary, you can also update them within the same section. After making the necessary changes, don't forget to click "Save Changes" to ensure your updates are stored.
