I suppose we'd better explain the "4 hour freebie".....
Once upon a time, in a Galaxy far far away and a long time ago, there was a rumour going around several forums that CEQUADRAT would be offering a free full download, over a 4 hour interval (midnight +/- 2 hours in a US timezone, if I recall).
I remember groggily awakening at 7am Sunday (UK) and going to the site - initially disappointed, but then applied a forced refresh and found it was ON.
Not sure if it was celebrating something, I forget if the date was significant.
Despite rumours that it, or something else, might be repeated, if it was, I've never heard about it.
