Personally, I like to put my macros in a workbook, using an Auto_Open event
to install a toolbar referencing the workbook macros. The end user can store
the workbook anywhere they want. They open the workbook, install the toolbar,
and access my macros via the toolbar. If I enhance the macro, I send the new
workbook to the user, they replace their copy with the new workbook, and the
toolbar continues to function. If I add a macro during the enhancement, I ask
them to re-open the workbook and install the toobar, which replaces the old
one, and give them access to the new macro.
In one case, I have a workbook, sitting on a intranet server, that 30+
people access at least once a week. Easier than installing add-ins for 25+ of
them, since there is only 5 in the group that know that Excel is more than a
spreadsheet viewer.
