How to send a patch in a proper way?

[Adam PAPAI]

Hi,

As of today I'll try to help and create bugfix patches for usr/src and 
usr/ports.

I've already done 2 patches and posted it to the -current list but don't 
really know what is the best way to post the patches. Who will "check" 
them? who will make the decision to use them? How should I send the 
patches? diff -u full path or relative path?

Is there any FAQ about this issue?

Thanks in advance,
