"Has the Brighton Co-op store got a time machine?" asks Chris Marshall after seeing its ad on Thursday last week promoting a one-day sale for members on the previous day.

"If so, I'd like to borrow it."

Terence Sinnott, from Brighton, is less polite, stating: "I have often accused you of employing uneducated, dyslexic staff but now we discover you have thrown the net wider and employ innumerate staff in the advertising department."

That's unkind, Mr Sinnott, but, yes, we made the error and published an advertisement apologising last Saturday.

A headline on our report on Saturday, April 3, about Jill Mercer quitting as manager of the World Web Wise project, which she managed for East Brighton For You, could have been misleading.

Miss Mercer, who has been employed on the project by the Chichester Diocesan Housing Association, decided to resign three years ago - as the story made clear - and not since the start of a tribunal examining an unfair dismissal claim by former project worker Robin Lucas. I am happy to clarify any misleading impression given.

Peter Arkell, from Hove, points out our back page picture story on March 30 about Brighton and Hove Albion players enjoying a paintball session should have said it took place at Albourne in West Sussex and not Aldbourne, which is a village in Wiltshire.

Peter, who hails from Wiltshire, says the village has been made famous by Barnes Coaches, which are based there and travel nationwide.

A picture of clouds on one of the letters pages in the morning edition of Wednesday last week described them as an altocumulus formation. Not so.

Denis Earl, from Hove, says: "As an ex-RAF navigator who was frequently lost and gazed at the clouds in the hope of salvation, I would have thought they were stratocumulus. It probably explains why I got lost!"

Our story on Thursday last week about plans for a post office at St George's Church in Kemp Town, Brighton, said it would be in the basement. In fact it would be on the ground floor and therefore accessible to all, says Lorna Ducharme, who is a church warden emeritus.

Stephen Rooke, from Portslade, says he laughed when he read our front page story last Friday about how thousands of tons of a kind of chemical used in terrorist attacks could be stored at a warehouse in Newhaven.

"Thanks for telling the terrorists where they can get this stuff, including a photograph of the warehouse," he says. "Can you also tell us where the key is kept?"

Rob Chisholm says the caption to a picture of a hang-glider over Steyning Bowl on Monday should have said the site is private and for use only by Freelight Paragliding, which he runs. For more information, contact Rob on 01273 628793.

Ralph Bicknell, from Southwick, says we deserve "an accolade for inappropriate journalism" for our Body & Soul article on Tuesday last week about contraception and in particular a picture of a woman holding two condoms.

He says: "The question was 'Could you trust men to take the pill?'. I have another one - 'Can we trust The Argus to keep within the bounds of decency?'."

Maybe not to you, Ralph, but I think most people believe sex education is a serious issue that shouldn't be hidden under the covers.

And finally, David Sanders, from Brighton, wasn't convinced by our picture on Wednesday last week of an Abba tribute band who are to perform at the Dome, where the originals won the Eurovision Song Contest.

He says: "I hope they are soundalikes because lookalikes, as you described them, they certainly are not!"
