I really wish this would be made a priority. Far too many people are completely ignorant to the rules and oblivious as to what to do here. A simple and short message is all we need detailing the most commonly broken rules and links to further guides and stickies that go into depth about things so they can read up on them if they wish. So many people just have no idea where to even find this stuff and Meta is usually the last board they go into so being directed to these threads when they sign up will be very helpful.
In fact, we have a large number of members who have little understanding of English or don't speak English at all, so the basic forum rules should also translate into all local languages on the forum.
Also, many new members don't have experience with internet forums.
I also see that many new members do not have enough knowledge and experience about crypto and bitcoin and write bad quality posts.
The welcome message will not solve all these problems but will help and should be introduced as soon as possible.
I mentioned somewhere that there should be links to the translated rules/guides as well.
