Hi Duncan,

could you describe the requirement more detailed ?! What are the minimum requirements ?

Thanks Klaus...

I need to stream videos and allow the download of PDFs. There needs to be a user forum and a payment facility. I appreciate there may not be one product that covers all these. I am looking at Moodle which I know a little about - but I am open to other ideas. At least 1000 users - possibly up to 5000.

Basically we are moving our language training - now with 35 years experience - online.

Gratefu for further thoughts. 

Hello.In your case, I would recommend Moodle.

I know there are special extensions for Joomla too:

https://www.joomlms.com/

https://extensions.joomla.org/tags/lms/

https://www.joomshaper.com/joomla-extensions/sp-lms

But a specialized system like Moodle would probably do better.

Thanks Aleksej. That is where my thinking is going. 

It's my pleasure.
