The tags I enjoy most are in the infidelity and abuse category. In other words cheating, most kinds of ntr, but not so much netorase. I also enjoy blackmail, rape, slave and so on.
As a person I'm very opposite the tags I enjoy. I'm always ready to help if I have the time. As for how I can help...
I have worked with proofreading and editing subtitles for over a decade. I have worked with computers for over 30 years and it comes easy for me to proofread game scripts for that reason. I've proofread 6 games so far. Five of them Ren'Py, one of them RPGMV.
I'm very laid back, so unless you're paying me for my service anything I do is entirely up to my schedule.
I will generally not accept requests to proofread games that aren't within my wheelhouse, meaning focused around the tags above. The exception would be if one of the more famous games asked me.. but how likely is that?
