Maybe an idea to clean the forum members, people inactive for more than 2 month can be removed.
Jesse (chi) seems to have trouble connecting to the forum, any suggestions there.
Yes but keep in mind that some old threads have nice content and you could delete those when deleting the user (depending how the forum works)
Content is preserved even if the author is deleted, but for the moment we don't consider the amount of members in the forum to be so large to be concerned about inactives. As for the problems of Jesse, could you please ask him for more details of his troubles connecting, because as far as we are aware the forum is fully functional currently.
