Well, first I think the plan is to get all the bugs out, and make it as stable as possible. Then they can think about adding more features.
There's only one thing needed... A client

I cannot agree more with Bungdi. Hopefully Chess.com listen to its members and have a client. Chesspark growth fast and keep its clients really happy because of that feature.
Question to Chessy4000, what other sites have "client"? I have been looking for that feature and I can't find any site that provide me with that. That was the main reasion why I joined Chesspark in the first place.

I havent come acrossany other sites that have the feature either. Would be good to find one so I'm able to play chess again the way I was able to!

well they are manly pay for sites not sure if I am supposed to mention them here, you can get free trials on them.
Chess.com has done a lot of good things but they are missing one compulsory component. A client. I have been a member of chesspark for a while and had never come across a faster, more reliable way of playing live chess. Whether it be 1min games, 5, or longer. The lag was almost negligible.
For all the chess.com users you probably haven't experienced the benefit of a client, but I'll assure you, all members from chesspark that have had to move over would be extremely dissappointed that there is no similar means or way to play chess here. Chess.com seriously needs to consider adding a client in as part of there package.
