You may wish to use the simple hotlink code:
<a href="/~wnki/cgi-bin/esubscribe.pl">Click here</a> .......

Or, you may wish to use a form. It all depends on look, feel, and inclination at the moment. Both options are available. To implement the hotlink just use a modified form of the code shown here. To use the min-form use the instructions below:

• #insertsubscribe#

  This will put a min-form at that point allowing users to enter a name and email address to subscribe to your website newsletter.

• Edit form text.

  You may edit certain portions of the subscription form -- just be careful. If you edit the wrong stuff it will stop working. If that should occur then strip the whole thing out and use the command code to put it in again and start editing all over.
