How do I attach a link?

[Whatadooo]

Sorry can’t find site stuff i’m I’m a kerfuffle I want to post but for it to make sense I need to add a link from my previous thread how do I do it?

Thanks

On the app you swipe the little arrow to the side of the thread Title you want and click copy, then start your new thread and hold down, click paste when it pops up (in the 'reply' box as if you were commenting)

Well it depends if you're on the app or the website, and a phone/tablet or a computer.
