Since you ask... Let's start with copy'n'paste your current sig in case it changes:

so i guess the the lesson learned is: "if you want a thing done well, do it yourself"

Sentences done well have:
1. A capital letter at the beginning;
2. A capital 'I';
3. Only one 'the' before a noun;
4. A full stop at the end.

Of course, someone may have written it for you. In that case it rather proves the point.
