E-Learning Platforms: Moodle and Blackboard

Not features. For a partnership your size it comes down to who administers it and what happens when the funding ends.

Moodle is open source, so nobody can withdraw it from you and you can host it yourself or pay a partner to host it. That freedom is real and it has a cost attached: somebody has to apply updates, hold backups and answer the call when logins break. If that person is one enthusiastic colleague, you have a risk rather than a plan. Blackboard is commercial and the support comes with the invoice, which is the same trade in the other direction.

The question to answer before either: at the end of the project, who owns the accounts and the content, and can you export both in a form that still opens somewhere else. Ask it now, in writing, while you still have a choice.

Nobody has asked that. Realistically it would be me doing the administration, alongside everything else.

Then be careful, and consider whether you need a platform at all. A learning platform earns its keep when you have enrolments to manage, progress to track across many people, and certificates at the end. If what you have is a set of materials and a group of mentors, a platform mainly adds a login screen between people and the thing they came for.

One further point specific to this audience. Every platform is another account, another password and another place where a woman's participation is recorded. For someone who has to explain what she does with her time, or who shares a device, that is a real cost. If you do run one, check it works properly on a phone browser, because that is the device most of your learners have.
