Hva skal jeg fjerne i koden for å fjerne en visuell link?

[Anterialis]

Hei,

dette er en plugin til wordpress som forteller om jeg er pålogget msn messenger. Men det er et par linker jeg vil ha vekk (se bilde). Hvor er dette i coden, med andre ord, hva må jeg slette i coden for å få vekk disse to linkene (altså hele den linja som sier "mutube >> IM Online" nederst i bildet)?

 

Dette er mest for morroskyld, og prøver å lære meg litt forskjellig av dette.

 

På forhånd takk =)

Ehhh ... nei? GPL er jo «copyleft» som er et «anti-copyright»-opplegg. Ergo vil GPL aldri gi deg den type beskyttelse. Hele ideen bak GPL er tross alt at du har frihet til å gjør omtrent hva du vil med programmet

Hmm, er det en annen lisens i GNU-prosjektet som beskytter copyrighten da? Mener å ha lest det en eller annen plass.

[ZoRaC]

Man kan ikke fjerne copyright-referanser i kildekoden, mener jeg.

Altså man kan fjerne utskrift, så lenge man ikke fjerner info om opphavsmannen fra kommentarene i koden.
