Recently active questions in twitterfeed tagged with feed

i recently changed to my own openid and deleted my old one before actually deleting the associated twitterfeeds. How can i remove my feeds from my old openid login ?

How do I make my feed ignore comments on my blog? I have the feed set so when I post a new blog update, it sends a twitter out. Well, on that same blog, I have a section that updates whenever someone comments. How do I make is so it does not send out a twitter of that person's comment?

I see the field for filtering "only" certain words -- can I do a command like -"Garbage"

if I don't want posts that contain "Garbage" in the title to be included? Thanks

I've just entered the URL for my blog, tested 4 times and it says my URL is not valid, even though it works great on Firefox and Internet Explorer. What could be the problem?
