The process of setting up a forum to send you e-mails when a post is made is called "subscribing". It is fairly easy to subscribe to a forum.

1- You must be a registered user on the AAVSO site (that is, have a web account). You don't have to be a member, but you have to be registered. You must also be logged in to your web account.

2- At the bottom left of the first post in every topic page is a "subscribe" link (you can see it at the bottom left of this post as well!). Click on it.

3- Three choices will appear:

  • Subscribe to this page - Check this off if you only want to subscribe to replies to this specific topic (for example, the Subscribe link on this post will allow you to subscribe to all new replies and edits to the topic "How to subscribe to the forums").
  • To Forum topic content- Check this off if you want to subscribe to EVERYTHING - any post or reply to any forum. Note that this means you will get a lot of emails!
  • To content in (NAME OF FORUM)- Check this off if you only want to subscribe to new posts or replies in the forum that you are currently in.

4- Click Save.
