Erm. Assuming you use a US keyboard, there is one interesting key on it. To the right of the letter M there is one that produces a comma and next to that one there's an even more interesting key that produces dots. Sometimes called "fullstops". Please try to press that key at the end of each sentence, followed by one or two spaces (that's the big button at the very bottom of your keyboard) and then before you press the key to produce the first letter of the following sentence, press the one marked "Shift" and hold it for a bit and only leave it after that letter was typed. It will make your posts much easier to read.
