This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have added private message attachments functionality to JForum 1.2.8. It meant only minor changes, and I think only those made to the security restrictions (that are tied to forum ids which private messages do not have) might create some conflict. I posted a question about it but got no feedback, so I will leave it like that for the time being.
