How can I add a (legitimate) Trade Line?

[Cliff Bradshaw]

I have a timeshare that I have been paying for since 2003 and have not missed a payment nor have I been late. I am sure this will boost my credit score dramatically and I would like to know if there is a way to add this account to my credit. The company says their policy don't allow them report to the credit bureaus but they will send documentation of the account.

Does anyone know how to get a legitimate tradeline added to their credit file legally?

Thanks
