Why I am not able to post a response on Mylot?

For the last couple of days I tried several time to post a reply on the following topic “search engine optimization tricks” (do a search to find that discussion dudes). After pasting or typing my response, when I click submit or preview the browser becomes blank and go nowhere. At the bottom left of browser ‘status’ shows as “Done”. Any one have any idea why this is? Am I blocked by Mylot? Or is it some browser problem? I tried both IE and FireFox. My account was created 3 days back and this is my first post.
