Service to the deaf and dumb

It is nice to know that the internet cafe is not only for gamers but also for those who are physically impaired. Right now, there are 5 deaf and dumb customers using the computers in the shop, chatting away (with sign language). Instead of using Yahoo Messenger, I notice that they (the deaf and dumb customers) only want to use Camfrog Video Chat. I do hope that they will tell more of their friends about the service provided here. Might need to install Camfrog on all the computers if more of them want to come here.
