Hello and sorry if this has already been discussed but i honestly don't even know what to search for.
I've seen on many wp blogs a list of categories on the sidebar but when i hover my mouse over any of them, the link shows-up like http://website/tags/cat-name . On my blog, the address is http://website/category/cat-name.
Moreover, on those blogs i saw, at the end of each post, there is something like "Posted in cat1, cat2, cat3".
Now, what do i have to do to have this on my blog as well?
PS. My PHP knowledge is close to inexistent so go easy on me. Thank you!
