When I first arrived, I wanted support and help with installing my OS Win 7. Immediately, I realized that there are many, friendly, knowldegable and helpful members here. (First thing I like)
There are many, many knowledgable people here; so if you have a problem there is a very short wait for help. (Second thing I like)
I also like that all the threads stay on subject. I belong to other forums and the topic wanders, many times ending up in a less than friendly discussion. (Third thing I like)
Finally, I like the fact that there are so many people with questions, some difficult others less so, that regardless of your level of expertise you can get a good feeling from helping someone with less knowledge than yourself.
