20. Do not include things like your post's 'nfo' or 'sfv' in your PAR set
Please don't include the files like an 'nfo' or an 'sfv' in the PAR set of your post, or at least make them "non-recoverable" if you do include them. That way it is not necessary to have them in order to do any PAR based part recovery. This is particularly inconvenient if you used a generic name for an 'nfo' file which could easily be over-written by a later download.
