OK, on the basis that it helps to know at least a little of what's going on, I've had word that some people are having trouble in posting comments on my Blog. Checking through the Blogger Beta "Known issues" pages, I found the following:
Users who have not switched to Blogger in beta will not be able to login to comment on blogs that have been switched. Commenting using the "anonymous" or "other" options will still work.
What this basically means is that for those of you who are not on Blogger Beta yet, you may have trouble commenting on my Blog as yourselves (ie. with your Blog identity) - but if you select Anonymous or Other (both of which are available as I've not set my Blog comments to be acceptable only from Blogger users - 'cos that's darned unfriendly, I feel !), you can still leave a comment - but please leave your name or a link to your Blog so I know who you are ! I hope this won't put people off leaving comments - I value getting feedback from my readers, so if it's having a hissy fit and telling you "We're sorry but we're unable to complete your request" try switching your "identity" to Other or Anonymous and leave me a comment... If you're still having problems, my email address is over in the right-hand pane (you'll have to scroll down for it, until I move it back up the pane - I was having trouble getting it to even sit IN the right hand pane last night, so once it went in, I decided not to push my luck and move it up, but I'll try that shortly !)
