@NicoDean Well, now I feel really stupid and lazy for not writing to the admins before. (I was going to do it eventually, I just procrastinated...)

Questions without answers are listed in "Unanswered" which is accessible in the left navigation bar, at least on my desktop browser and my tablet (iPad). (I can't figure out how to see "Unanswered" on my phone.) No need to wait a year. ... I'm not one of the downvoters, but I wonder if some of the downvotes are because you are suggesting a feature that already exists, in fact quite prominently?

I've edited the question to try to be less judgmental about possible (imagined) motivations for asking about one's own conjectures.

Oh, Open Problem Garden seems to be dying --- last update in 2017, and it won't let me create an account. Shoot. We can't direct sincere askers to a dead site.
