All the lists (except for the two Croquet lists) are managed by Mailman, so these instructions work for all but those two lists.
To Subscribe:
Go to the linked page and follow the instructions. That is also the page to handle your subscription options, such as daily digest
You can also sign up for an "announcements only" version of the list, if the regular list traffic is too heavy for you and you just want to see the major [ann]ouncements. To do this, you must subscribe first, then go to the "edit options" button of the administration page, and then turn on the "Announcements" topic category.
To View the Archives:
Use the archives linked from the administrative page (one message per page)
Use Gmane. It presents either a threaded view or a blog-like view
Search the Squeak Mailing List Archives using Google
Q: How do I search through the archives?
A: Use the Google Search Tool above.
A hint for Beginners
The Squeak Mailing List is highly active. So should we just subscribe if we already feel confident in Squeak (should i say smalltalk ?). Else you'll probably feel like me: lost and flooded :).
I don't know who posted this, but beginners are certainly welcome on the mailing list, and in fact a significant chunk of the mailing list volume is newbies asking questions and getting answers. It's certainly true that the mailing list has a lot of traffic – I'd guess about 30-150 messages a day, depending on the day. -Lex Spoon
Sometimes the mailing list gets busy with people discussing advanced topics, but there are a lot of beginners lurking on the list too, who may also benefit if you ask a beginner's question and get a discussion going.
If you feel at all unsure about asking a beginner-oriented question on the Squeak list, you can always add a [newbie] or [beginner] tag to the subject of your message.
Alternate methods for reading the Squeak Email List
I have subscribed to the squeak@yahoogroups.com list. I receive all of the emails just fine, but when I want to reply, I receive an error email back from the list saying that the list doesn't support it. So, where are all of the emails coming from? Is it the 'dev' list mentioned above that just gets copied to yahoogroups? Seems odd. A little guidance is very welcome. JasonRogers(jacaetev@yahoo.com)
It seems that you have to register with the squeak-dev mailing list, despite being a member of the Yahoo! squeak group. Frank Shearar
Another way to read the Squeak Email List is as a newsgroup, via the gmane mail-to-news backend. See http://www.gmane.org/. To use gmane, the news server is news.gmane.org, and the newsgroups are listed. For instance, the main squeak-dev list is the newsgroup gmane.comp.lang.smalltalk.squeak.general
