Fixing it:
Saluete ad omnibus!
Ad lenguam latinam cum 4chane deseo parlare. Bona lengua latina est!
Protips:
a. Verb at the END of phrase (most of times). This is not English.
b. No silly v/u or j/i distinction. Latin doesn't use that shit. This is not Pedobear's Proto-Italian.
c. "Est" imposes nominative, not genitive.
4. "Parlare", not "locutare" - more informal.
5. "Cum" imposes ablative, 4chan ends in -n so is 3rd declension, so it's "4chane", not "4chano".
6. "Latin" is an adjective in Latin - "ad latinam lenguam", not "Latina".
