I emailed Brooks regarding the support desk and he said they're actively manning it; so I'm really not sure what to say short of the email directly tip above (which you've done).
As for the "company appearing non existent", as of January 2015 all development of UBB.threads is being handled through
UBBDev (the modification community that I'm now operating as of a few years back), we agreed with Brooks to publish 3-4 releases per year of the UBB.threads product.
