Note my amendments to your post. Remember the rules of written English:
- Start every sentence with a capital letter.
- End every sentence with a single, appropriate punctuation mark.
- Do not put a space before a full stop, comma, question mark or exclamation mark.
- Always put a space after a full stop, comma, question mark or exclamation mark.
- Enclose words you are querying inside quotation marks "like this" or put them in italics like this.
You will notice that rule #2 on the list I gave was "End every sentence with a single, appropriate punctuation mark". Even a sentence as short as "Thanks" or "Thank you" requires a final punctuation mark.
Note that "u" is not a word. It's "you". Please use only full, standard English words on the forum.
In addition, there is no need to write a new post to say thank you to anyone. In the bottom left-hand corner of every post is a "Thanks" button. Click that to say thank you.
