I read with interest your advice on sending e-mails by mobile phone. However in trying your method I discovered that my Nokia 7110 does not have the symbol "@" in its keyboard. I presume it must be possible to overcome this, but how? - Austin Kenny, via e-mail

Hi Austin, if you press the star key - bottom left corner, below the number 7 key, this offers a series of symbol choices, one of which should be the @ sign. It's a button that most of us, this reporter included, only come across by chance. It is a very handy button containing 30 symbols, including the pound, dollar and euro sign. The number 1 button also contains seven of the most commonly used symbols, including full-stop and comma.

I've been using e-mail for quite a while now, but I am having trouble with sending attachments. Do you have any easy-to-follow advice for me? - Tom, via e-mail

Firstly, it is useful to explain what an attachment is, as a lot of people may not know. It is a means of sending text files, pictures, sounds and video across the Internet.

A lot of the difficulties that people have with sending attachments is that the various e-mail packages all deal with them in different ways, and web-based e-mail facilities are different again. The good news is these differences are mainly stylistic, rather than an entirely different approach.

At its simplest, it is a case of sending a couple of attachments to yourself until you are confident that you are doing it correctly. With Pegasus mail, for instance, you first click into a new message as normal. Then you choose the attachment option, or hit F7 (a grey key at the top of your keyboard) as a shortcut.

From there, click on a button on the bottom right corner, called "add attachment". This brings you to a window of the type you get when trying to open a file in, for instance, Word for Windows. Click through that in the way that you would open a document until you find the one you're looking for. Double clicking on the file name will automatically attach the document.

If you want to attach a file that you have previously sent in this manner, clicking the "recently-used files" button offers you a self-explanatory list.

The process for other e-mail packages, such as Eudora or Microsoft Outlook, is similar. Often the principal difference is in offering shortcut such as Ctrl-H (or Apple-H for you Mac users) rather than F7.

For attaching video, sound and pictures, the process is the same. Just double click on where the file is stored.
