..which isn't made any easier by the fact that hexus emails arrive several days after the competitions started .. or not at all.
I sometimes get emails twice (like the "i'm watch" thingy), and for some competitions, I don't get a notification email at all (like the Crucial and Plextor SSDs, the PNY GTX770 or the AOC monitor from a while back).
I have yet to get an email notification about the "new" Coolermaster competition from Dec. 6th, even though I've entered that one already and got the confirmation email
If I wouldn't bother looking at http://hexus.net/competitions every now and then, I'd miss quite a few of them.
