[TYPO3-english] Accessrights for pages / Many FE Groups

[Erik Svendsen]

If you are using MySQL 5.0.3 and newer, VARCHAR can have a value of 
65,535, but it's shared among all columns, so effective length are 
lower. But try with different values.

The use of varchar isn't directly an misconception, but also related to 
lack of functionality in earlier MySQL versions.

TYPO3 V5 is using a complete different structure, build upon Content 
Repositories.
