If you want to be taken seriously, it pays to make an attempt to correct your spelling mistakes; especially in the title.  Some have an automatic spell checker that underlines mistakes in red as you go, or you can do a spell check at the end. 

There are also many free online spell checkers, you can cut and paste your document into those and use them to check your spelling for you.  Spell checkers won't pick up every single mistake, however it is an improvement and especially helpful if you need help in this area. 

If you only need help to spell the odd word, type it into google search or one of the many free online dictionaries and you will be offered suggestions and explanations that should help you choose the correct spelling.
