If you are talking about a blog here on AllDeaf, then you need to do the following:
At top of page, you will see User CP, Blogs, FAQ, and so on, click it and go to "Your Blog" It will come up and say "?? has no blog entries to show" ?? being your user name. Then off to the left, under your avatar, there is an Options box. In that box is the option to "Post to your Blog". Click that and go for it.
I myself do not have a blog. I just opened up and extra window and was logged into AD on both tabs and went back and forth to write out all the steps, clicking as I went.
