Status on the other coins that have been requested:

GrandCoin - According to the main thread, super blocks grant additional coins so I can't accurately calculate the total supply based just on the block count
ASICCoin - Waiting for the Coinex API issues to be resolved
XenCoin - Block explorer seems stuck http://xnc.webboise.com/chain/Xencoin
ElephantCoin - Same issue as GrandCoin, unable to calculate Total Supply when super blocks are in the mix

Thanks for the feedback and patience, working hard to add new coins and implement the suggested features.
