I used this service today, because the sender (Betcoin.ag) included zero miner fee.  Transaction was of course stuck in limbo for 8 hours, and probably would have never confirmed.  At that point I noticed there was no fee attached.  It cost me ~$2 USD to accelerate transaction 0660a3c06d84da2bef2a524b25abe05457b0901f1ffd7b7b4d70f241688961cf of almost 4 BTC.  It was worth every penny to me.

2 confirms within 2 hours.

Bummer man    6 minutes into the only game with players all day (the freeroll) game gets paused and message from host we are shutting down for an upgrade........

Where are the WPN shared tourneys?  I only see the Betcoin ones

http://www.gambit.com/?ref=Mike_R now offers backgammon games for bitcoins.  Not many players yet but site is relatively new.  I have deposited and cashed out and both were very quick and easy. 

I was having the exact same problem with a HIS 6850 I just picked up this week.  Took me a day of researching and cruising the forums to figure it out.  Turns out it was a problem with AMD SDK 2.8 and even though I was uninstalling it and trying other versions, until I found a post that said I needed to manually remove the files amdocl.dll and OpenCL.dll from the c:\windows\system32 folder before installing another version of AMD SDK.  Once i did that then reinstalled version 2.5 all was fixed and shares were being accepted at ~210 Mh/s without OC.

I like Coinbase.  They are one of the few exchanges (maybe the only one)vthat lets you ACH to and from your bank without going through a third party payment processor. Now that they secured $5 million in new funding hopefully the trading halts for liquidity issues will be less frequent.

Coinbase is plagued by delays and long periods where trading is halted entirely.  Just today they were not allowing any buy/sell orders for ~ 5 hours.  I was finally able purchase by trying every half hour till it accepted my order.  Best to have accounts on multiple exchanges as they are all subject to DDOS attacks and other technical issues.
