Thanks for asking! If your works are posted on AO3, the existing tagging is likely to be enough.

If not, notes on AO3's main categories for warnings (graphic violence, major character death, rape/noncon, or underage sexual activity) would be helpful. I've also found in previous rounds that people sort themselves into "willing to read smut / not willing to read smut" so, again, if your works aren't currently published on a platform where the tags indicate whether there's sexual content, that's really useful to know.
