This may come across as pedantic, but the terminology on the page is a bit imprecise and may suggest a lack of sophistication for somebody selling a financial information product. You're not helping anybody avoid missing out on an IPO because you're not helping anybody be part of the IPO market itself. (Generally only big investors with a relationship to the underwriters or friends of the issuer get to be participate in the IPO market, i.e. to buy shares in an IPO.)
You're offering to let people know that shares will be available in the secondary markets the day after the IPO is priced and shares are sold (often buying FROM people who bought in the IPO). The distinction here is important because in an IPO that "pops" on the first day of trading, somebody who buys shares on the secondary market in normal trading is not going to be able to buy them at the IPO price. (They may even have a hard time buying them at the opening price in secondary trading...)
