Just a tiny note of explanation for

the erratic behaviour of your feedburners - for those that have them. Often, despite my efforts to have a professional presentation here, typos slip under the radar and I simply don't see them. When I eventually notice or someone tells me, the corrected version often ends up being resent out as 'new'. This can be irritating. Sorry about that, but I think it is better to get the mistakes fixed as soon as I'm aware of them.
