I'd like to contribute a file to the forum, but can't

[unmerged(155883)]

I've developed some useful spreadsheets for playing EIC and I'd like to contribute them to the forum. Unfortunately I don't have permissions to attach files to posts. How can I go about making this contribution?

Thanks,
Tom Dacon
