Sometimes too much of a good thing can be a bad thing. If you’re having a problem with individual users submitting too many proposals (usually so they can have better odds of being selected, but for whatever reason), you might want to try setting a submission limit. That way, users will have to pick their best papers to submit and won’t be able to flood the selection committee with “junk”.
To take advantage of this feature, all you have to do is set the Individual Limit (under “Submission Settings”) to the maximum number of submissions you want to allow from an individual user.
For example, if you want to restrict users to three submissions, enter “3”. (If you do not want to place a limit on the number of proposals a user may submit, enter “0” or leave the setting blank.) Once a user has met the submission limit, he will still be able to create proposals and collaborate with other users, but he won’t be allowed to submit any more proposals for your call.
