Where do member's find out information about forthcoming IPOs? A platform will only list them if they are participating, so up until now I have a Google alert on the phrase "Admission to trading on AIM", but that doesn't catch them all. I do read the IC and Moneyweek, but they don't list them all.
The LSE itself has details:
