Should we recommend also disabling Link previews as mentioned here https://discuss.privacyguides.net/t/critical-flaws-in-desktop-session-messenger/16674 ?

And other problems mentioned?

Suggested change

	Session allows for E2EE in one-on-one chats or closed groups which allow for up to 100 members. Open groups have no restriction on the number of members, they are hosted on federated servers operated by the communities themselves, and moderation policies are determined by each individual community. However, they are not as private as one-on-one chats or closed groups.

can we link to a resource which explains why this is the case in more detail? or explain why ourselves

that might be a better idea.

I got it from https://getsession.org/lightpaper/pdf. Their docs are pretty lacking tbh.

EDIT: https://docs.oxen.io/oxen-docs/products-built-on-oxen/session/guides/open-group-setup and ofc you can check the whitepaer https://arxiv.org/pdf/2002.04609.pdf

I'm not sure the information about federated servers or moderation policies are particularly relevant, since virtually all group chats are subject to the whims of the group's admins, that's not exclusive to Session.

Instead, we could link to the hosting docs for people who are interested in the federated server aspect, and just focus on the fact that messages are stored without encryption on the server which is the most relevant thing to note for most people I think:

It is also possible to [host](https://docs.oxen.io/oxen-docs/products-built-on-oxen/session/guides/open-group-setup) or join an open group which can host thousands of members, but messages in these open groups are **not** end-to-end encrypted between participants.
