When logged in to Undertow, click on your name on the top right corner which
will direct you to this page:
http://suzannevega.com/tools/cs/user/EditProfile.aspx?ReturnUrl=/forums/default.aspx
In
the e-mail tab, select Yes for Receive E-Mails and Enable E-Mail Notifications
and save the settings.
Then, within Undertow, open a thread of interest and
click the button "Enable E-mail Subscription" which lives on top of the first
post. This way you can select which threads you would like to follow via e-mail.
The new boards do not allow you to reply by e-mail, so you'll need to use
the link in the e-mail to return to Undertow in order to make your post.
As of right now, you will not receive an e-mail for a post that you make, but I will see if we can make this an option on Undertow and will get back to you.
