To answer some of your questions there is quite a lot of HELP information written by the most experienced people on WikiTree.
At the very top right hand corner of the Wiki screen there is a 'Help' drop-down box. SIX lines down is the 'Help Index'. If you click on the 'T' you can then find help explaining 'Trusted List'.
On the Help drop-down list, the 3rd line says 'Contact Mentor'. Maybe you would like to contact someone who wishes to be your personal helper?
Please understand every member of WikiTree is a volunteer which means no one gets paid for contributing to WikiTree or answering questions.
I hope I am helping you,
