Best place to submit ideas for a new product idea/inventions?

[J]

if you idea is so good, then write all your thoughts along with any drawings, how it works etc---just everything on several sheets of paper, sign and date every page, place them in an envelope, take it to a post office not in your neighborhood and mail it to your home as a certified letter.

when it arrives, never open it. place it and the receipt in a safe place.

now you can talk to whomever you want and be somewhat protected.
