Ive been having a million questions running though my head but no place to ask them until I finally remembered this website has a forum!
Here they are, answer one or all, everything helps.
1.) Can I/is it difficult to set up my own pool with me and my friends? Is it worth it?
Difficult for your average Windoze user, sure. Not difficut for anyone who has ever tried to install Linux and enjoyed the learning experience. It's not a project for non-geeks.
2.) How fast would my computer have to mine to make solo mining worth it? Is there hard numbers for this?
This is case specific. No one can rationally answer this for you except you. My best guess is that it's probably not worth it. I don't mine, myself.
3.) I currently mine at around 95Mhash/s on this computer...The first night I started mining I found a block. How lucky was I?
Incrediblely lucky. Go buy a lottery ticket before it wears off.
