Design of the subfora

Hello, some time ago we had voted to set up another subforum for the “old” series 3XX, 4XX. Unfortunately, this has been postponed until now, because there is a desire to “overall” change the structure of the subforums. In addition, it is also about the length of the textual description of our foren, which is generally a bit long. Well, here I stand now. . . . . . . I could live well with the previous structure, just add the 3XX, 4XX, but can They cut down the terms, but how?
