Not to mention, the "
Beta Testing UBB.threads" wiki entry has been kicking around since April 2015 (linked to in the top portion of UBBDev's main forum page), with little interest being shown by the user base. If the user base where interested in bleeding edge coding, they're more than welcome to request access to it; it is a process that needs to be followed since the coding is not stock and is not 100% ready for "prime time" usage without the knowledge needed to assist in debugging issues.
