Why can't some users post comments on my blog?
Some blogs might not allow people with Internet Explorer to post comments because of certain tools in their sidebar.
A possible solution for this would be for the user to switch to a different web browser such as Mozilla FireFox, which should work fine with all blogs.
Also if you have a member blocked, they cannot post in your blog page. You can check here to see if their username appears in the 'Blocked Members' list at the bottom of the page.
