[quote name='DontHurt']yeah i have the same issue. i only look at the first page before posting. i think if its a good deal and not on the first page, i think a people will appreciate a repost. most of the time i see expired post because people are replying to old treads. they should have an option to sort by submitted date.[/QUOTE]
The first page is not really enough for you to determine if it's a repeat - usually, it takes two or sometimes three pages just to cover the last 24 hours.
Whether a repost is justified is almost a subjective thing; I'm in favor of it when the alternative is that the deal is buried in another, absurdly long thread. In this case, though, the thread on the Steam sale has consistently been on the front page of the forums for the past five days, and the deal itself wasn't exactly a secret since it's on the front page of Steam's website, client, and the notifications that pop up when you log in.
But then again, the mods had no problem with reposting KOTOR, L4D, or any other one of the Steam deals as individual threads, so...
