123guestbook allowed this but they closed soon after I made an account.. i killed them =(^O_._O^)=

https://atabook.org/ Oh nvm this looks to be it. Sharing in case anyone else is looking too

smargb does allow it! but unless the person puts their email in they won't know if you've replied

Htmlcommentbox was great for me! Tho I eventually moved out from it, and decided to try and build a custom one for my site :p

Thanks everyone, I appreciate it !
