From day one we allowed each user to connect to more than one ledger in uCollect. Now each ledger may be accessed by more than one user.
From your Edit Organisation page (if you are an Admin for that Organisation) you can invite another person into the uCollect organisation. If they ar enot yet a uCollect user they will receive an email inviting them to create their profile. If you give them Admin access they will be able to access the Edit Organisation page and modify subscription, gateways and users. If they are not an Admin they will only be able to search contacts, edit contacts and see Collection History (including downloading Upload files).
