Just a heads up and WARNING.

be very weary of trying to either register, or re register DxO's Film Pack 3 free offer.

AFAIK, the offer finished a long time ago, and it's not on DxO's site as such.
But there is a site that leads to DxO's webpage if you search for 'Film Pack 3'.

My advice is to avoid this site completely!
I don't think visiting the site will harm your PC, but do NOT try to register here.
There may be a very high probability that the registering process is compromised and any info you supply may be used nefariously.

Out of curiosity, I tried the registration process again to see what'd happen, and I think a spammer got my email address and used it to send spam across the net.
I now got a ton of return receipts to emails I never sent .. ie. spam.

The last thing I used that email addy for was for that registration process ... be warned.
