Hi nmf thanks for the suggestion.
Looked at the software but I use Windows 7 so not compatible. I have started to use Windows Word to simply copy the text, I can input about three and one half lines, then then paste it into word. I then use the word count feature to check that I am not over my limit.
The agency is to update the hardware/software for the site fairly soon so I hope that the restriction will be removed.
Thanks again for the suggestion.
