I integrated Alex’s disclaimer into the template. In case it needs to be changed and I am not available - the disclaimer text is in forum/styles/serenity/template/overall_header.html, lines 316-320.
If anyone changes the disclaimer text, please document the changes in this thread!

NOTE: After changing the text (or any other template file for that matter), it is necessary to purge the cache (ACP -> General -> Purge cache) for the changes to take effect.
