Been doing a lot of work around Discourse lately and really love the software! Very well thought out, thank you!
One feature request: a link that automatically opens the reply composer, or asks the user to login and redirects them to the reply composer after a successful login. Basically exactly like [Creating a link to start a new topic with pre-filled information](https://meta.discourse.org/t/how-to-create-a-new-topic-link-with-pre-filled-information/28074) but for replies.
Thank you!

I use something like this:
> [@Opening a reply window via URL](https://meta.discourse.org/t/how-to-open-reply-window-via-url/44781/18):
>
> I use a simple theme component for this in my instance. Below is an adaptation from mine – which also accepts #upload (a new reply opening the upload window on desktop) and #edit (for wiki OPs) in addition to #reply. It needs some work, like avoiding setTimeout and correctly managing draftSequence (I don’t think topic.draft\_sequence is right), and I don’t know what would be the best practice here. That said, it’s working fine for me. Navigating to any topic like /t/[slug]/[id]#reply will open …

This seems to work. I added the code in the API initializer of my theme. Thank you!

I just realized that this solution doesn’t ask the user to sign up or log in, if they’re not.

I think you can have some logic in the theme component to show the login page if the user isn’t logged in.
What I currently do, linking from another site, is enforcing the login flow like this, but I’m not sure if this works if you’re not using SSO:
`SITE_URL/session/sso?return_path=/t/slug/id%23reply`
Having it in the theme component is better to avoid unnecessary redirects anyway, I’ll try improving it when I get a chance (I’ll comment here if I do).

Just tried it. Returns a 404 since I don’t have SSO enabled I guess 🙂
