How do you insert HTML and files/attactments to the replies and stuff ](*,)

(a href=http://www.google.co.uk/)google(/a) <--this is how you make a link to another site, except you change ( to < and ) to >. However, you do not need that on this site, as you can press URL which is just below the Subject box and then type in the url, then press URL again and you are done.

As for files, if they are on the internet, all you do is find their url and do as shown above for a normal url. If the file is offline there is nothing you can do, except upload it to somewhere on the internet.

Hope this helps.

Here is a good site for free file uploading, there is a maximum of 50MB but no bandwidth restriction:
http://www.freefileupload.net/

Im looking into whether it would be worthwhile to include files/attachments into the replies

Not for the moment.

Try to do that Matt, it would be great, then I could show the flight plans for the airline lol It's not to big of files.

From deans post

Use http://www.freefileupload.net/ for now
