Answer 1

it is my first day in these forums...it takes time to get to know how things work sumwhere....but kind of response im getting is very discouraging....im sorry if i havent followed any rules....but my intentions arent bad in any way...all i can say is sorryy...nd if nobody can help me in my query and problem it is ok....1. Don't cross post. Many people especially the ones that answer a lot of questions do not like it. And I have never seen anyone that claimed that they liked it.
2. Use english as best that you can. Do NOT use sms type speech.
3. There is a big difference between being able to help you and wanting to help you. The two are not the same.
