Any advice about the advantages and disadvantages of using the Actuarial Grads Network Form to circulate your resume?

It seems like if you use it you're relying on someone else to be your primary contact with the company, and you don't know who got your resume, you loose the ability to follow-up directly with companies, you can't send a personalized cover letter for resume, etc.

If you use the form, and also send resumes directly, companies may feel your'e bombarding them.

Any thoughts on personal experiences would be appreciated.
