You need to highlight and copy the thread address from the address bar, click on the globe/chain-link icon in the other thread and paste the address. Or paste directly in the post. Either work.
If you do the chain-link, you can name the link like so by replacing the highlighted part of the hyperlink thingy.
Does that make sense?
