Hello Nicholas!

 NB> Is this command needed?

Yes. It enables the list mode. All following areas are rescanned without the need to type %rescan in front or /r at the end of the lines. This is pretty comfortable. Especially because a simple <area> means:

<area>                       <- Subscribe to the area

a new subscribtion.

Correct. Rescan always needs a target.

 NB> Does '%RESCAN <area>' already cover the correct way to go about this?

Yes. That is the reason why %RESCAN <area> is the first line of the rescan commands in the %help message. The normal workflow should be to search a text from top until the first hit found the keyword.

 NB> If '%RESCAN <area>' can also be used this way:

 NB> %RESCAN
 NB> <area>
 NB> <area2>
 NB> <area3>

Yes it can. That is what the empty %rescan line set up.

 NB> or

 NB> %RESCAN <area> <area2> <area3> ...

I did not found that in the helpfile so i think that does not work.
The <area2> is reserved for the N parameter to rescan N old messages.

 NB> Maybe just making the first option:

 NB> %RESCAN <area> ...

It is the first option in the helpfile and should be the first option that would be found.

 NB> .. and elminiating the blank command altogether would eliminate any

The confusion was because the empty %rescan line without following echos did not produced an error answer. Teach the users to who to do this RTFM thing and you would avoid more confusion in the future.
