As of today, an opportunity is closed after 5 providers have applied to it.
We chose this solution for two reasons:
For providers applying to the opportunity, it maintains the competition at a reasonable level. If more providers were allowed to apply, the competition would be too high and the opportunity wouldn't be valuable enough.
For the project poster, it keeps him from receiving too many sollicitations and be overwhelmed by messages, emails, phone calls and requests coming from providers who applied.
This is a temporary solution and we're actively working on a more sustainable product feature.
More info will be coming soon.
