I just did a test and you are right, I was under the impression that anyone could message me on Patreon, but it seen that only Patrons can. The worse is that there is no option for me to open private message to everyone, this suck.
Well, there is also my email in any case: griskai.yt@gmail.com
I think your question was wen 0.5 would appear in here? For now I don't have an answer, will keep developing it on Patreon and at some point it may appear here.
