Information about SPACs, differences between regular IPOs and SPAC IPOs, and terms of lock up periods

Hey everyone. Just wanted to share some informative links I’ve come across while doing more research on SPACs. Below are two links that give pretty good details on what a SPAC is, why it is different from an IPO, how they’ve grown in popularity for companies wanting to go public, and how the terms of the share lockup periods for each work. There is also information about how risky short positions are against SPACs. Hope this is beneficial and welcome any additional info to be added.
