This has bugged me for ages and tonight I have had ER spoilt so I have to get this off my chest!
Not everyone on here uses active conversations. Some of the other search screens show quite a bit of each post, even without opening individual threads.
Putting 'spoiler alert', a single blank line and then spilling the beans isn't enough. If you must post spoilers, please please have a bit of consideration for others and take more care.
You need at least 4 lines into the post to keep the stuff hidden. And for those who do open threads but read from the bottom up, putting a warning at the top of a post but not the bottom doesn't help either.
Right, rant over. No doubt I will have to bump this in the morning so people actually get to see it, but it just had to be said!
