Topic Type
As I am starting to go through tool entries and I have questions about the entry, I think that some of them might best go to a private e-mail, and some are better to post the the associated forum. I think that adding a more social aspect to the tool wiki interface would really help improve the content. It would be nice to be able to see who was the last editor without going into the revision history, and then be able to directly contact the last poster to that wiki.

Agreed, private messages enabled, still needs links though
