[TYPO3-english] Login, edit own data, categorize

[Denis Torgal]

Hey friends,

I need an extension, where users after login can edit their data: Name 
of organization, Address, maybe upload their logo. Then they should also 
assign themselfes to categories. But only up to 5 categories.

It is like tt_address but every users should only be possible to edit 
his own data and how to limit the assign to categories?

With which keywords I could search therefor in TER?

Any suggest could be helpful. Thanks in Advance.

Denni
