Trying to figure this out!

Ok, so the last time I tried this, I typed my blog into my journal, copied it, and attempted to paste it in the new post section and it would not take it!!! What did I do wrong? Can i not do this? If that is the case, I will keep my other blog, and get rid of this one :( I really like this blog, with one little exception... if I cannot write in my journal, and then paste here.. what is the point? Help me someone please?
