I'd Like To Comment But Apparently I Am Not Allowed

So I have recieved roughly 4-6 comments across the range of my blogs, and you have no idea how greatful I am for these comments. I would love to be able to respond to you wonderful people who are posting comments, especially where there is potential for debate and discussion as there are few things I love more. Alas apparently blogger, or maybe the computers I am using, will not let me. I click view blog, I click comment, but it doesn't recoignise me, I select google account for my profile and it tells me I am not allowed to view this page. A thousand appologies to those who have been good enough to comment, hopefully I will get to the bottom of this.
