I have now downloaded and installed the BETA 4.3.3 (which turned out to be 4.4.1) from the original post in this thread. I now find that I am an "UltraPeer", and the quality is now 'Turbocharged". Under 4.2.6 I rarely saw more than five users downloading from me; under 4.4.1 I have 20 active and 10 queued! That is a lot of difference! (Now if only I had had it before I lost those two huge downloads. )
