Lots of users will look at a huge stack of incompletes in a browse as a sign of Leeching too
Its not very encouraging when you do a browse, 5000 files, to see a gazillion incompletes, a bucketload of albumarts and mebbe 5 or 10 completed files that the user hasnt yet moved to their non-shared library...
So the solution is simple: Keep your incompletes list modest. WinMX will only load so many files with AFS and AEQ set anyway, I think mebbe 20 or 30, the rest are loadable but dont have AFS and AEQ set
