My hosting company has the MD5 encryption ready for me now and when I implemented the hack I got a version error from Dynaloader looking for v2.16 and finding v2.20. It should be running sometime today though. I'm sure that Infopop is giving this a high priority. They do have to balance efficiency, load, and ease of installation and portablility of UBB as a whole.
That's why I think that the haxxors of the UBB world need to put some of their attention to the short term.
