Due to the recent upheavals with the MPAA ratings systems I'm in the process of adopting the rating system used over at the National Library. This rating system is being used on my site with their knowledge and permission.

These are the general ratings:

• CHILD - suitable for all ages (formerly G)

• YTEEN (i.e. younger teens) - some content may not be suitable for children (formerly PG)

• TEEN - suitable for teens and above (formerly PG-13)

• MATURE - suitable for mature readers (formerly R)

• ADULT - adults only (formerly NC-17)
