on my family site under my family tree and the manage tree there is no gedcom download option at the bottom of the page as shown inthe help section. Where else can i download the gedcom file?
part 2 of my question is how to attach a person in 2 places on the tree at different places
When checking your account details, I can see that you are not a site manager of the the family site "patel Web Site" and this is why you are not allowed to download a GEDCOM file.
You have 2 options - either to ask the site manager to download the GEDCOM file and send it to you, or ask him to promote you to be a site manager. Thus, allowing you download the tree.
Regarding the 2nd issue - please view this FAQ item -
