Contact Information

Just a quick question. Where might one contact 343i if they wished to submit fiction to them? I know that typically, companies such as this do not accept content as a rule, and prefer to approach writers themselves.
Nevertheless, I wish to send a manuscript to 343i in the event of another Evolutions-type project. Worst case scenario, you will have some extra place mats to kick around the office (and who couldn’t use more of those?)
A PM would suffice if 343i doesn’t wish to post this address. Thanks in advance for your help.

*Edit. I plan to include return postage and an envelope for 343i’s convenience.
