Here's my complicated ten step process for when I absolutely need something quoted.
I'm using Chrome, you may have to accommodate for differences in browsers.
1. Find post you want to quote in tab B.
2. Right click quote on any other post on the topic you want to post in in tab A.
3. Choose copy link address.
4. Open tab C, paste link but do not proceed.
5. Return to tab A, and click the title of the message you want to post, just above the date.
6. Look at msg in the subject bar. The number after that is the post you want to quote. Copy it.
7. In tab C, change the number after quote= in the address bar to the one of the post you are quoting.
8. You now have the message and date, but to make the link work, you need the topic ID in the quote too. This was not done earlier because in the URL, it also controls what thread you are posting in.
9. Go back to tab B and grab the topic ID from the address bar, after topic=. Paste it in the quote code after topic=.
10. You now should have a functional quote, with proper date and link. Preview it and test it, though.
Locked, as usual.
