To be honest, none of these have fantastic Latinitas, but generally the authors at least welcome corrections
- Adventures of Cicero & Virgil
- Ozy & Millie in Latin (translated by Dominica from the conventiculum)
- Sluggy Freelance in Latin (seems to be experiencing some technical difficulties)
There used to be a (rather poor) Latin translation of "Sev Trek" as well, but that was years ago, and I can't find it now.
