As noted here, it sounds like their website was compromised: http://forums.watchuseek.com/f2/password-changes-4566037.html They've stated: The extent of the breech and what member information (if any) was stolen is unknown, but it doesn't sound good so far. If you were using the same password on WUS as Omega Forums or any other sites, please consider changing them immediately to help protect your account and online identity.
I love the effortless simplicity and smoothness at which OmegaForums operates. No other forum of which I am a member is so well run.
Always use a different forum password here to the one you use elsewhere please, especially on Verticalscope sites. There isn't much news out on this yet but from what's appearing from some foreign hacker groups it likely isn't limited to Watchuseek and could cover many Verticalscope sites again.
