So, you may have looked at stuff and seen “F4F”, advertising projects on a famous project (that is something even I don't understand).
Since this is for New Scratchers, here is an explanation: F4F, means Follow For Follow (it gets pretty annoying, because it means that if they follow you, you follow them… who made it? I don't know), now for Remixing, that is for using the other project as a tutorial, or a way to collaborate, but most New Scratchers just Remix it, and just put their name in it and remove the Original Creator's name and call it theirs. (Which Breaks The Community Guidelines, Under ‘Exact Copy’, and can get reported, and just don't remix a project to make it yours, do it to Learn! Collaborate! And More!

Hello! It's great that you want to help out other Scratchers. However, I think we have enough guides in the forums at the moment. Please feel free to welcome new Scratchers on the group welcoming topic or on individual topics created by New Scratchers.

Other places that can always use more helpful Scratchers like you, are the “”Help With Scripts“” and “”Questions About Scratch“” areas - please use them as designed, by responding to topics created by folks with problems to solve

Finally, a really good place for Scratch guides is the Scratch Wiki - check it out and see if it's something you might like to work on. They have a number of guides - and great organization.
