We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Most newcomers to this forum do not read the page on formatting code. This leads to them posting questions on the forum, but without formatting their code properly. Then the older members have to tell them to format their code properly. Some examples -

I'm sure you all must have seen some others yourself.
My proposal is simple - whenever a new member joins the forum, a message should (automatically) be sent to them telling them to read that (and other) page(s) before using the forum.
