You may wonder why none of the questions in the Coccinella forum were answered. You may also question yourself why no comments has been made to blog posts. Is the Coccinella project really so silent? No, the reason is simple: comments were just not visible for anonymous users.
When I was IM'ing with someone this morning, I gave him a link to a comment with a possible workaround for his problem. He said he couldn't see the workaround. Ooops! It came out I forgot to give anonymous users access to comments. My mistake.
