PMwiki: Great for Micro-ISVs…
This is a little late, but I’m going to comment anyway 
A couple of weeks ago, Bob Walsh posted about plans for his mymicroisv.com site and mentioned that he was going to add a wiki to the site. I added a brief comment over there about PMwiki being easy to setup and use.
I just thought I’d add that I also have a private copy, sorry not ‘net accessable, that I use almost every day to track anything and everything related to my business. Any ideas I come up with for ThoughtFiler or other potential products or services go there, budgets, plans, goals and pretty much anything else I need to record about the business goes into the wiki. Makes it quick and easy to retrieve later.
