"Module 1 - always worked by word of mouth. Many times they wanted to make a website, but they received a lot of questions from programmers, and the price tag “bit". And also marketers and programmers requested a lot of meetings, in general, it was not up to work. Here we were presented with a ready-made solution, I can't say that there are a lot of applications, there are.
Module 2 - In principle, over 19 years of work, we have accumulated a lot of templates, examples of nodes, developments. They were scattered on flash drives, disks, and so on. It was difficult to search. The wiki managed to systematize it in one place. Well, plus - it works fast.
Module 3 - Finally, all documents are at hand, on the phone and you can share documents. And I am also glad that seafile works on our server."
