I'm in contact with a coin developer who is looking into the XCN sync issue. I will give him a bounty from my wallet, if you wanna contribute you're welcome.
In case he can't/doesn't want to fix, the bounty will be open to everybody.

Meanwhile, I'm organising the information for the following:

- new website
- new wiki
- new BTCtalk thread
- new wallet windows build (with fix, if in time)

As a reminder for people who aren't following the thread, and because the OP is outdated, we already have:

- new wallet github with compile fix: https://github.com/pallas1/Cryptonite
- new explorer github with fix for new php versions and incomplete blockchain: https://github.com/pallas1/MiniExplorer
- new explorer running on http://xcn-explorer.selektion21.de/
- poloniex wallet fixed, withdraws and deposits enabled, trade paused
- btc38 wallet still not synced, but I'm in direct contact with their tech people to fix it

A little team is forming around  this, let's try to make it the new XCN crew! :-)
