Is there a maximum number of resources on a given project?

Hi Everyone:

We are  new Clarizen customer and are trying to decide whether to have one Administrative (non-billable) project or multiple for different managers.  Both could work, but we are wondering if there is a maximum number of resources we can assign to a project?  We may have 80-100 resources on one administrative project with multiple direct managers approving time for their reports.  Any gotchas with doing this?

Thanks

Lori
