OK, well first of all you need to know how to link to an actual post, as opposed to just a thread: click on the
icon in the top left hand corner of the post you wish to link to, next to where it says 'by boboff on ....' This will reload the page with the correct URL for the post, so just copy that from the address bar. It should look something like this:
Code: Select allhttp://chrismoyles.net/phpBB3/viewtopic.php?p=366057#p366057
(note that after the 'viewtopic.php', there is a '?p=' and then a number - if you were specifically linking to a thread, there would be a '?t=' and probably a '&f='.
Then, to customise the text that forms part of the link, click the 'URL' button and you should get the opening and closing tags. Just before the first ']', put an '=' and then paste the URL you copied. Then in between the '[url]' and '[/url]', you can put whatever text you like. It'll look something similar to this:
Code: Select all[url=http://chrismoyles.net/phpBB3/viewtopic.php?p=366057#p366057]This is the text to be linked[/url]. This text will not form part of the link because it is outside the [url] and [/url] tags.
Hope that was easy to understand... and if it was, I hope it wasn't too patronising.
