An alternative would be to upload the text and code to a site like pastebin.com or hastebin.com; either site should format your BBCode perfectly fine and have it compacted to about 30 characters for you to send off to a staff member.

I personally don't see the board being utilized enough to justify making it; if there's anyone who's wanting to shoot off a suggestion it's relatively easy to just PM a member of the staff group you're making a submission for.

Alternatively, you can simply post the implementation here and suggest that it be added somewhere into the main forum.
