[2019] A mail....

Yes, we send such an email. One player can gets:
1)Three bonus codes. With activation limit one per account - you can activate 1, gift other 2. (So each player can activate only one code from the set, and each code can be activated once).
2) Three invitation codes - you can invite friends.

i3 with integrated can work, it really depends on the gen, but if that laptop is so old that hadrware doesn't allow upgrade to W10 - it seems playing WoWS won't be possible.
