Hi, I am new to WP but have been able to work out most things and get my site to a reasonable level, though I know there is a lot more that can be done.

One thing I haven't been able to work out and I am sure it is actually quite easy, is making an email address active so that people can click on it and send an email straight away, without having to copy and paste it into the email.

Can someone help me with this.

this is straight HTML - do a google search with 'html mailto' and you see lots of explainations. Here is an example

<a href="mailto:test@somewhere?subject=Test subject">email with default subject</a>
