We renamed from TFCPH.com to InstantFreeHosting.com in January 2009 to make it clearer we offered free hosting as a sub set of what we do.

We were also previously using a post-to-host system (e.g. write 30 forum posts and get your free hosting) with TFCPH.com but converted to a Get-Free Hosting-Instantly system with InstantFreeHosting.com. This is the main difference and what the mysterious "TFCPH" was.
