RSS-can't make it work

I have spent 1.5-2 hours on working it all over again, but still couldn't make it work!
I went to the very first beginning, made everything as 'public' as possible, I ticked all the 'yes', agreed on everything, I went to all the sites you suggested, I prescribed something on each site, I even received something in my email, still, my link doesn't work!
I got all the staff(who are doing this blog stuff) in the library to check my so many steps to see what was wrong, no one could see any.
What went wrong?
I can't figure out, the only difference was I use my working email went registered (@aucklandcity.govt.nz) . Is it not a public one? so can't be shared?
I read your comment, and so did my colleagues, none of use can solve the problem, we even could not find those tags you mentioned, not on any page! where are they? the more we searched, the more we puzzled, 2 hours later, everyone got lost.
anyway, blog is something for people to use when they don't have or want to social contact, it is another channel. for me, it seems a channel of communication between you and me, I do according to you instruction on your comment, but i can't see you.
I am sure only you will read it, as I don't seriously read anyone else's
I watch a lot new technology on newspapers and TV, such as iphone, tabletop, etc.,high price, but people still fight to get one. I've got a very advanced mobile phone, a gift, but I only use the most basic functions, good to know it can do a lot of things though.
maybe one day, our library will have a table top, customers can play whatever they like on the clever coffee table.
