What is the "law" or right way to use Snippets in your own filters ?

IN the Filter Forge Wiki you can see this in the Snippets part

The snippet serves for finding those basic effects that have proven to be the most useful to filter authors

As I have began to make my own filters, I want to be sure to make the things in the right way and respect the work of other authors, so please I want to know:

Are they totally free to use in any filter you want, and you can mix a few snippets in your filter?

When using the choosen snippets you just give credit in your filter to the author (or authors) of those snippets ? And that is all ?

I have been looking for more information about FF snippets usage in the wiki and help manual but did not find it yet,so that is why I am asking it here.

Please if you know wh ere can i find more information about this, it will be very welcomed and and thankful if you could put the link to it.

Thanks very much for your help

IMO, giving credit for a snippet is optional. I even read on one snippet where the author said to not give him credit, because credit is being overdone. Lots of these snippets are standard methods.

OTOH, it is nice when people create snippets. It makes it easier for the rest of us. And it's nice to be acknowledged. So if you do want to give credit, you can do it in the filter description. Or, you could click the comment button for the snippet, and post a thanks and credit in the forum.

Thanks very much for your answers and comments now I know more about how to use the snippets

So if I use any snippet I will for sure give credit and thanks to the author in my filter. Why would I not do it ?

I am NOT like others that could use snippets or filter parts and DO NOT give either credit nor thanks and respect to the author. I am refering to This thread here and also this thread too
