What does this entail? Two things:
1) There is a "Leak" tag that should be used in any post discussing unofficial spoilers outside of the Unofficial Spoilers subforum. The leak tag looks as follows:
[leak]This is a leak[/leak]
Will render as:
Unofficial Spoiler Discussion
This is a leak
2) There is an Unofficial Spoilers subforum of Previews. This forum is only visible to members who have opted in to the See Unofficial Spoilers group.
All discussion of unofficial spoilers and leaks within the Previews Forum should be kept within the Unofficial Spoilers subforum. But given the new opt-in nature, there is no longer a requirement to obfuscate the content of the leaks from thread titles.
All discussion of unofficial spoilers and leaks in other forums should use the leak tag.
