Installed and working on 3.8.1 - thanks!
Added information for those concerned about the time to set this up. We have over 3.5 million posts, so I tried this first on our backup forum and the install screen timed out due to (I believe) PHP settings. So I examined the setup and found the line that modified the post table
Code:
ALTER TABLE post ADD ame_flag TINYINT DEFAULT '0' NOT NULL
So I just ran this via mysql when the board was quiet, which took about 20 minutes, and then did the install which just skipped over this stage as it was already done and completed with no issues. I have done this for other modifications that alter the post table as well and have never had trouble.
