This is what i so much hate in total with EE, even it is “flexible”.
If there is some guru out there, please make such add-on that allows you to use custom wiki templates, similar to Custom System Messages, what is a must for all EE-based sites imho.
Sidenote:
As i have spoken to several developers in the near past, all of them has said to me that they never use EE Forum Module, i bet this goes also when its all about wiki..
So, read between the lines: both are dying modules? Hope not?!?!?
