WiseNotes
A Wiki for tracking notes - simple and easy!
*** NOTE *** There seems to be some problems in Windows 10. This should be fixed by going to the WiseTech\WiseNotes folder in the x86 prog files and running wisenotes.exe as admin. Update - 8-16-2016: You can now delete old notes and categories plus you can search notes by name! I work in IT and most of my jobs I've worked at have always had a generous learning curve and not only because IT can be difficult at times. Often times, its because documentation is lacking or is poorly organized. So I created WiseNotes to remedy that for myself. This is the standalone version utilizing a MDF local DB file but it is also available in a central MySQL server version. This is a simple yet effective wiki as it has a spot for categories and a spot for notes belonging to that category. If you like it and want to support future development (and my 4 hungry kids, hehe) then you can click the donate button! But no pressure! Its free -
