https://Ice-dice.com is considering offering an IPO to raise some fund for the bankroll and hire some marketing to grow the site. The site launched 3 weeks ago and it's been growing steadily with good feedbacks from both users and investors. Now we are thinking of taking it to the next step and doing an IPO. I'm not familiar with the way bitcoin companies IPO, can someone send me some info on how it's done?

Some of my questions are:
- How do we issue shares to sell?
- How do we keep track of who has how many shares?
- How do we pay dividends?
- How do we buy back shares?
- How do we list on bitcoin stock exchanges?
- What is a good bitcoin stock exchange?
- What are some of the pros and cons of IPO and selling shares?
