Cheat Engine Forum Subscription
As you've noticed, Cheat Engine now costs money, but to maintain the forum some extra money is needed. So, from now on you have to pay to access the forum.
The price isn't really all that expensive, for a 1 week subscription you pay $50, and for 4 weeks only $150, that's a bargain if you keep in mind all the valuable data stored in the forum (trainers/tables/addresses/scripts/codes) , and not to mention all the humorous and community binding posts in random spam.
If you subscribe for 6 months or longer, you even get access to the RSS and RSS2 sections, and if you register for a full year, you even get 100 free +rep or -rep depending on your choice, and the cefquest will give you invulnerability for the first 25 battles
