Many users should be able to access comp.lang.apl via a newsreader such as tin or Free Agent. If you have a World Wide Web browser such as Netscape, Mosaic or Lynx, you can access the newsgroup by specifying the URL news:comp.lang.apl. The group can also be accessed via e-mail using the APL-L mailing list. When you subscribe to APL-L, all comp.lang.apl postings are sent to you via e-mail, and you can post to the list by sending e-mail.
To subscribe to APL-L, send an e-mail message to firstname.lastname@example.org containing the one line "SUBSCRIBE APL-L". A message containing further instructions will be sent by return mail. You will have to send an "OK" message to confirm your subscription. Immediately after confirming your subscription, I recommend you send listserv a message containing the one line "SET APL-L CONCEAL". This will prevent your e-mail address from being harvested by spammers who would like to send you unsolicited commercial e-mail.
To post to comp.lang.apl via e-mail, send a message to email@example.com. The message will be forwarded to all APL-L subscribers and posted on the comp.lang.apl newsgroup.
You must be an APL-L subscriber to post to the list. If you want to post directly to APL-L without receiving their mailings, subscribe as directed above, then send firstname.lastname@example.org a message containing the line "SET APL-L NOMAIL". This is useful if you want to be able to post from multiple accounts without receiving the APL-L mailings at each account.
Another useful feature of APL-L is its archive. All APL-L/comp.lang.apl messages are saved and can be retrieved on a monthly basis. For example, to receive messages posted in August, 1995, send an e-mail message to email@example.com containing the line "GET APL-L LOG9508". Beware that the return message may be rather large (500,000 bytes or more, depending on the month). This is a handy way of checking for any messages you might have missed while following comp.lang.apl via a newsreader. You can access the APL-L archive even if you are not a subscriber.
