Uservoice have changed their service agreement along with other things, and as we aren't receiving as many requests as we were in the past, it doesn't make sense to set up another feature voting alternative for the time being.
I've downloaded the existing requests that we'd collected from Uservoice so that they don't get lost. The existing NCrunch/Uservoice system will be taken offline in the next few days.
So we're back to having feature requests on this forum again :)
