If you have written a comment here in About Translation, and you do not see it, let me know: another blogger told me that her comments never appeared here.
I never delete a comment just because it is critical of something I wrote. The only comments I erase are those that are clearly spam (along the lines of “excellent post, come and see my web site at xyz.com”).
Comments to older posts go through moderation (to cut down on spamming), but I normally publish them within a few hours. Comments to recent posts should appear immediately, unless they are caught by Blogger’s spam filter (but I check the quarantined comments often, and allow all those that are not spam).
So, if you do not see your comments, write to my gmail address (RSchiaffino {at} gmail.com). When you write, include the text of your comment, and tell me which post it refers to: if I cannot find your comment among those waiting for moderation, I’ll post the comment myself, mentioning that you sent it. I’ll also try to see with blogger’s technical support if anything can be done to prevent comments from disappearing.
