Good news. Quark explorer
http://qrk.blockr.io/ is now on the correct Quark fork ! Now,all major Quark explorers are on the right fork!
There are now 2 things to be done:
1. Cryptsy to fix Quark wallet.(They were always on the correct fork and they need just to update from 0.9.2.5 to 0.9.2.6)
2. Mac users need 0.9.2.6 wallet too.There were no Quark updates for Mac users from 0.8.23
