Can anyone tell me how to add direct links to webpages on my 'Signature'? Please

(They show up as red links on the bottom of each post. In the 'Signature' box)

I tried to copy and paste a link but it just displays the text without linking to the webpage.

Ive seen people linking to their favourite posts or webpages and i cant work it out.

Thanks.

You have to place the link between: [ URL]  and [ /URL]  (close the spaces between [ and U )

However, outbound links are not allowed in the signatures. Only Peachy thread-links

Thank you.
