Hi my name his Jerade, I heard about this site through buddy of mine. However I don't know his username on here. I like watching basketball, getting to know God more, and reading comics. I encounter an issue on here: You guys don't post URL links but these type of links: CRC32, MD5, SHA-1. What are they and how do I use them to get the files ? My friend also told me he learn alot from this site like having two or three OS on his system, so point me to where I learn to do that. If there is anything I can help with site let me know. Nice to meet you all.
