XVII Members are asked to log in to the forum at least once per year
I've noticed that those members who don't log in for a whole year are members who never return.
Maybe they are still present but, if so, with a new account and a new username. Since, until now, other members may have been addressing questions to these inactive members, by private or public message, and wondering why they are getting no response, I prefer to make it clearer by adding an item to the forum rules:
Members are asked to log in to the forum at least once per year.
The accounts of members who have not logged in to the forum for more than a year are deleted.
Those who have had their accounts deleted from the member list may re-register at any time.
