6. Put the ep # before the part count in your binary post's Subject Line
Design your subject line so that the parts of each episode are grouped together. As most here sort by Subject, posts that interleave together, such as...
Foobar [22 of 33] ep 05 - FB05.part
Foobar [22 of 33] ep 06 - FB06.part...
Foobar [23 of 33] ep 05 - FB05.part...
Foobar [23 of 33] ep 06 - FB06.part...
Foobar [24 of 33] ep 05 - FB05.part...
...tend to be very irritating -- consider this a *comfort* nag. This specific case exhibits the most common mistake -- the poster didn't put the ep # before the part count.
...and, remember, keep those subject lines short....
