Slovak translation of the Mailing Lists webpage

Hi there, 
i found a bug on the slovak (slovenčina) translation of the
debian mailing list webpage

https://www.debian.org/MailingLists/index.sk.html

at the subscription/unsubscription section right after the
[email protected] link there is missing a text "which" before
vaša.email@adresa.

The correct phrase is:
Ak nie ste si istý, či ste prihlásený konferencie, pošlite e-mail na
[email protected] s textom

"which vaša.email@adresa" 

v tele.

Regards, Ti
