1. Group By Category (use the Group By Box) and then select that group and
drag to the Outbox.  They'll drop into a new email.  You can then drag their
names into the BCC field.

You could also email merge to this Category group - select them, Tools |
Mailmerge | to email | type subject line | OK | insert the Merge Fields (
not word fields) click Merge to email | OK. Ta da!!

2. You'll get better functionality from using Groups as described above.
And there's no way I know of to make a DL from a Category group.

I recommend everyone learn how to manipulate data in table views using the
Field chooser, Group by box and Sorting by clicking on column headers - have
a play.

Change to the By  Category view, click the first contact in the category,
press shift and click the last contact in the category, right-click the
selection and choose "New Message to Contact".

Since you can send a message to everyone in a category, a DL isn't required.
