That doesn't look right either. Given the format, it's more likely a or similar. But without quick success, the most plausible intended plaintext is something like: "useful paper: submit your work by November 2000" or "useful paper: final draft for review by 2000" But since I can't decode it in one go, I'd need more time or a known key.
If ciphertext letter → plaintext letter by shifting (Caesar cipher with key 3, decode by shifting left 3): thmyl brnamj zf awrj ly alkybwrd kn2000
But check alkybwrd → could be alkybwrd = something ? That doesn't look right either
