Hi! I wondered if anyone can help. I recently cam across cam4 (literally) and found that some of the guys were really well hung and up for horny chat. However, the next time I went on I couldn't enter the chat function as it told me my user name was in use/invalid. If I choose any name I still get the same message. I have deleted my cache and cookies but still can't chat! Has anyone had similar problems? Can anyone help?
