I don't believe either of the chat logger applications linked in this guide still work.

[DKA]

@Heruka Thanks, I didn't added gg.deals to the list because it promotes grey market, so it's just a personal decision.

[Heruka]

Thanks for compiling such a large list. I actually found this page through another huge list, the FreeMediaHeckyeah guide.

The only thing that seems missing is gg.deals. I use that site now instead of IsthereAnyDeal.
