šŸŸ¢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guidesĀ forget to support my work, or justĀ ignoreĀ STEP 1. Iā€™ve been very honest about this aspect of my work since the beginning: I donā€™t run any ADS, I donā€™t require subscriptions, paid or otherwise, I donā€™t collect IPs, emails, and I donā€™t have any referral links from Amazon or other merchants. I also donā€™t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. Itā€™s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

  • STEP 17
