It would be nice to have the option to create an RSS feed on the forums, that way we can be alerted when there is a new post made. Now a days people have them sent straight to their phone which makes it that much more instant.
A current alternative you could use is by going to Profile -> Preferences
Then set Always notify me of replies : to yes
This will send an email when there is a reply in a post you have made.
Another alternative is when you click Post Reply and before you click send there are a few ticky boxes, one which is Notify me when a reply is posted. This will also notify via email.
I remember that geekpolice has a feeds system, but i forgot where to get it... I have subscribed to the technology news forum. Wait till doc replies and he will show it to you
If you are looking to subscribe to a specific forum, tell me which and I'll give you the link. If you are looking for RSS feeds per reply on your topic, then it's currently not available.
