A PICTURE SPEAKS A 1,000 WORDS
A suggestion for the Forum homepage which all could see.
Perhaps a simple way to give structure to the location of topics in the forum, is to show at the entry point to the forum, a model of a beehive, with relevant click points.
For example, click the roof to write about the roof.
Click the broodbox to write about the brood box, etc. etc.
When someone clicks, the beehive element, a suitable link could be automatically generated.
