"You can give your memoried entries the same access levels your give your journal entries. Set an access level for this memory now."

I'll worry a bit that it will lose clarity if it's shortened from this, given that we're walking our DW adopters through an unfamiliar set of concepts. (I did remove the intrusive "that", which is against DW Style.) Perhaps: "You have the same control over your memoried entries as you do over your journal entries. Set an access level for this memory now."
