People often insert links to other web address's - and this is a very useful facility, however if not done correctly it causes pages to be difficult to read on many screens. The answer is simple, and I MUST ask you all to follow this method.
COPY the URL link, then using the little icon of a chain link ( above in the small toolbar on top of the post box ) drop the window down, PASTE the link into the section marked "Link URL".
Then, in the box marked "Link Title" insert a brief description of the link, such as "see here" or similar.
Finally click " INSERT " and jobs a good 'un
