I am started to use Umbraco. But I found there is no form engine. I cannot create a contact form without coding. But I found there is a good contact form package, Cultiv Razor Contact Form. That is easy to use too.

Recently, I went a microsoft meeting. There were a number of people tried Windows 8.1 Preview. According to what I heard, although it will be not very stable in some situations, they are happy about the improvements, such as better sky drive and windows store. The most interesting thing is everyone mentioned the "Star" is back!

We started to build ios app again. But I drop iAd banner on the panel and run the app. I got this error "Could not instantiate class named ADBannerView".

I found facebook messenger apps has voice call function. Actually, I believe this function are in there for few months. But recently, I found that accidentally. While I opened a conversation and clicked "i" icon, which is the contact information, then I found there is an option for "free call". Then I tried that in Android. The voice quality is not bad, that is better viber. But the webpage has not this option, that is too bad. This option is not obvious in the app. A lot of friends don't know about that. Anyway, that is a good function to try. That is free and acceptable voice quality.
