Hello from Maryam

[D Foster]

Hi Maryam, welcome to the friendliest site that you will find and the only site that I have come across with the most information that you will find all backed up with people who have the problem which means that any questions you ask will be answered by the same people who know what they are talking about from personal experience.
There is nobody trying to sell you expensive rubbish as they have on other sites as Fred will not allow it just truthful discussion so have a good look around and ask any questions you like.

Dave
