[TYPO3-doc] Spam filter prevents editing article

[Daniel Bruessler]

Hello Joerg,

:-) Chomsky and Hopcroft, nice!

I just use a regexp, that is enough -- and 3-4 times a year I have to
explain why I use it. Until mid of september I do the wiki-upgrade and
when Sebastian has time for it also the SSO. So could be mid or end of
september.

Cheers!
Daniel
