Hello GRIDNET team,
It seems your web site moved to a SSL but you forgot to change the links given in your ANN/Bounty and signatures.
Old link was
http://www.gridnet.org/ (Not working)
you can redirect all request coming to old link to new site(
https://gridnet.org/) until you change all the links.
Do this change ASAP otherwise people will think this as SCAM, all official sites are down etc..
