Add a new rule, “Intelligence”:

Each Caveman has an Intelligence statistic, which is tracked in the GNDT and which may not exceed 100. ‘Intelligence’ may also be referred to as ‘Smartness’. New Cavemen start with the median value of Intelligence among all Cavemen, rounding up if necessary.

Cavemen below a certain Intelligence may be prohibited from using certain numbers, terms or words in their proposals. If the author of a proposal breaks one of these rules (at the time the proposal is posted), any admin may flag that proposal as illegal at any time before resolution so that it ceases to be a proposal. This does not apply to core proposals. The rules are:

* Cavemen with less than 40 Intelligence may not use words with more than three syllables in their proposals.
* Cavemen with less than 30 Intelligence may not use any number larger than 10 in their proposals.
* Cavemen with less than 20 Intelligence may not use capital letters in their proposals. Admins may opt to change all capital letters to lower-case in offending proposals instead of flagging them as illegal.
* Cavemen with less than 10 Intelligence may not use any punctuations other than full stops (periods) and question marks in their proposals, and may not use words with more than two syllables.

Set the Chief’s intelligence to 80, and all other Cavemen’s intelligence to 5.
