Many people have the good habit of preparing their work in a word processor where they check their grammar and spelling. Then they save it locally before copying the work across to their blog (or other online service). This is a great idea for those wanting to publish their accumulated work in some other format later.
This procedure however results in strange formating, font and layout problems. The solution is to copy the final version to the little program called ‘Notepad’ that is one of the accessories that comes with Windows. This strips off all the ‘formating stuff’ from the word processor (that you cannot see) and allows the final destination service to format the work correctly.
