Not limiting over the Net
I am 13 and have been programming in VB For like 4 years and started QB When I was 8. I have mastered Network Communications, but still am having trouble with DirectX. I signed up on RentACoder and got a job right off. I didn't talk about my age/education. I didn't put : I froze my computer 18 times trying to program in DX. I just don't go for DX Jobs. I put stuff about all the protocols I've mastered/network stuff I can do and post that and go for network jobs. No one asks about my age. No body suspects I am some 13 year old geek. I just program their and it works out... I started of from VBWorld and stuff. I've learned that the yonger you are, the less you can tell people about you because they will look down on your age. My advice is to hide it unless you are older.
:p I have also read that mentions of MSPaint aren't good in yoru resume :p
