i'm writting this to tell about the CAPTCHAs thing,that sometimes appears to we get the right letter.The symbol of OMEGA came to me,but in the list to pick it,or in the chart of the greek aplhabet,there's no OMEGA.i took a screenshot of the symbol,and it's saved on my computer.So if you want check it,i can post it in photobucket or in another site.

sorry about my bad english.Being a brazilian,my first language is the portuguese.
