Thank you very much for these resources, will begin to read them shortly, and then hopefully I will be able to make contributions!
No problem. I added some additional links to some tools and resources that I forgot to include.
But back to the original topic.
I got into glitching when I found some forum topic about missingNO. It was back in 2006 (IIRC) when TRsRockin was alive. However, back then I couldn't understand English, so I had to guess what everything meant or ask my mum to translate it for me.
But in 2010 or 2009 I found GCL. I had become better at English and I started learning about less well known glitches. I tried some of them myself and I started to become interested about technical details behind the glitches so I started lurking here.
