Alphabetical Order for Authors in Computer Science I was wondering, in the field of Computer Science, if there is a convention for acknowledging that author ordering for an academic paper is by alphabetical order, not contribution.

I know that in CS, alphabetical ordering, isn't all that common, however due to a lack of internal consensus, alphabetical ordering would be preferred in my situation.

Even in fields outside of CS, is there a convention for perhaps indicating in a footnote that the author list is alphabetical and NOT by contribution?

EDIT: To elaborate a bit more, after examining the question posted here, our field would likely be considered 'computer systems' (rather than theoretical computer science) where it is stated that the first author is usually the team lead. However in our situation, as I said, we are having internal disagreement over which person would be considered 'leader', and I was wondering what the best way to indicate equal contribution, or perhaps use alphabetical ordering to avoid the issue all together. We weren't really expecting to submit our work for publication (we're undergraduates), so this all has been rather unexpected.
In theoretical CS, alphabetical order is the norm - see the relevant wikipedia entry.
