That's the only way that I can get my subscriptions to RCU but I haven't tried switching back over yet. The problem that I see is that I only get sent one notification per thread subscribed to and unless I have replied in any of them since changing over to my Yahoo account I won't get any more to those.

I've got my account set up so that I'm automatically notified of replies. In your normal reply box, you have two boxes, one that says "Notify me via e-mail when someone replies" and the other, "Return to Forum after posting" and below that the "OK" button to post your reply or thread.
Nopw, way up at the top of this screen in the right corner in yellow there you should see either "Remove subscription" or "Subscribe" and "Printable version" next to that.
I've found that if I unchecked the box below then changed the one above to "Subscribe" then I got them through Almost OnLine.
I'm a computer idiot and somehow I figured this out. I get lucky sometimes. The next thing is to get AOL to fix the problem. Maybe we can get Marc to change "blackhole@.........." to something else as blackhole seems to be the word that isn't allowing the e-mails to be recieved.
