First of all, thanks to everyone on the Flarum team for the installation guide. I've managed to successfully create my own forum despite the lack of advanced computer skills by conscientiously following the document.
Now, I'm at the point where I'm setting up my email configuration. I went ahead and established my Mailgun account, then entered my API key and domain in the admin panel. When I clicked the "Send Test Mail", I was able to receive the mail without performing this part of the guide: "To use the mailgun driver, you'll need to install the Guzzle composer package (a PHP HTTP client). You can do this by running composer require guzzlehttp/guzzle:6.0|7.0 in your Flarum install's root directory."
My question is this: Since I was able to successfully send a test email, do I still need to install the guzzlehttp/guzzle?
Thanks in advance for all the responses.
