If you want to purchase Photopost you can do so here
http://store.yahoo.com/techimo/photlic.html I think there are many public boards available which are integrated nicely and no need to have a username/password for. This thread is quite old and dealth with a older version of Photopost. If you want to see working integrated copies of their software you can visit my forums link in my profile. Photopost integrates with the Threads database normally. There is a hack here which makes the Photopost styling change and default to Threads providing deeper intergration.
