ASTCT Communities are the best way to connect with your fellow ASTCT members. This page serves as a resource to introduce the online communities and provides details on how to configure your membership settings and participate via the forums.

How to Post in a Discussion Forum

The discussion forums replace the previously active SIG listservs. To participate, you must be a member of the community. Once you have joined the SIG community, you can participate in two ways.

  1. Log in and Participate Online
    Log in to your ASTCT account and navigate to the SIG Community page. Click the "Visit the SIG Community" button under the relevant SIG to navigate to the community home page. Scroll down to the Listserv Forum section, or click the "Discussion" tab. Click the "Post to This Discussion" button to begin your post. You will be required to add a title to your post. The text editor has standard formatting options, if you wish to add links, images, or other text formatting. You will also see an option to add attachments if there are files you want to share with the group. You can also modify your signature before clicking "Send" to publish your post.
  2. Participate via Email
    Each SIG community has a designated email address which can be used to publish posts to the online forum. You can visit the community homepage for each SIG to find this email address. Please note: you must be a member of the community for your email post to publish in the forum. You can add an attachment to your email if there are files you want to share with your post.

How to View or Upload Files

Each community has a file library where members can upload files to share. Attachments to discussion forum posts are also automatically added to the library. From the community homepage, click the "Library" tab. You will see the list of folders within the library. Click a folder on the left and the files in that folder will display in the column on the right. You can view files online, or depending on settings, can download for offline viewing. Members can also add comments, or follow a file to be notified when it is updated or when other members comment.

Manage Your Email Preferences

You can configure your email preferences for each SIG community, depending on how frequently you want to receive updates. You have a few options for notification settings.

  • Real Time - Receive an email every time someone posts to the community forum.
  • Daily Digest - Receive one email a day with a digest of all posts. If there are no posts on a given day, you will not receive an email.
  • No Emails - You will not receive any updates via email. You can still participate and view posts by logging in to the online community.

To update these settings, visit the SIG community home page and click the "Settings" button next to the community name. Select the setting which best applies to you and click save. You can change your preferences at any time.
