Fencer: I have just spent 10 minutes trying to figure out how to respond in the blog section???

I have made a "new" log in etc., but dont see where to click to make an entry, or where to click to make a response? i tried clicking on someones name, like Fencer, which is clickable, but took me to an email page to write a note, and after I did this and went to send, it said that fencers email addy was not formated correctly to send it? I just got more frustrated and came here.
