App/otu/new
From mx Help Wiki
There are two ways to create OTUs. Both start by clicking on the New OTU link.
- You may create a single OTU by filling out the form.
- You can create multiple OTUs at once by clicking on the Include all children? checkbox. This creates an OTU for the chosen taxon name, and every child. Be careful- you may be creating more than you wish, and at present you have to delete OTUs one at a time.
