Submit portable freeware that you find here. It helps if you include information like description, extraction instruction, Unicode support, whether it writes to the registry, and so on.
FYI, notes are saved by default in a filesystem database of folders (for notes groups), 'Index.txt' files (for group list and groups indexes) and numbered files with no extension (for individual notes). The latter are simple plain text files, i.e., they remain easily viewable/editable outside of Notesman.
