1. Linden Lab has no plans for users to define second name, which has been discussed in the official forum.
2. The configuration is generally related to the video card. The machine performance is good and the video card is very strong, but it is futile to not meet the SL configuration requirements. For details, refer:

3. Download the client program from the following link:
Http://secondlife.com/community/downloads.php
The position of the client program download column is indeed a little inconspicuous.
4. In fact, hipihi is doing very well, but there is still a lot of distance than Second Life. I hope this program can do well.
5. in terms of making money, I personally think that the current time is not mature for everyone, and the cost of land is very high. It is not a day's work to integrate into other people's communities. It also requires a lot of patience and energy to practice skills, in short, we need to make a lot of effort to make money.
