I was just wondering if I was missing something because like you said other sites do it and it makes it easier for me because I don't have to remember to check the website. I just check my e-mail and it's right there.
Not a big deal though, I'm on here so often I'm sure I won't miss any responses.
There may be another way to do it, but when you are posting a reply look further down the page at the "options" section. One of the options is to "notify me when a reply is posted." You can also turn on the feature as a default through the user control panel | board preferences tab.
Ah ha! I don't know why I didn't see it earlier, if you want to subscribe or bookmark a thread that you haven't posted in.... scroll to the very bottom of the page. In the blue bar on the left side are 3 links, board index, subscribe and bookmark. I knew I had seen a link somewhere.
