  • if you want any advice on how to use this program pls contact gülbik

  • Why must the manual be online? Isnt it best to have an offline manual, like in a PDF? Does the latest release have such a manual with it? Must I install the program to find that it has no manual except the online manual? My point is I dont want use the connection to nor can I count on being able to go online with absolute certainty. If I could not go online I would have no manual for the latest release and so could not use it. Online manuals make no sense except it pleases the dev because his or her package is smaller, that is why, correct? I have never understood online manuals. It seems to just be self serving. Yes youre the dev but thousands dont have a manual and cant use your prog. What if someone has no internet access? I know everybody is doing it, but that doesnt make it right. Is that why you did it? Because everyone else is doing it? In this case online manuals alone I feel is a definite blunder. I know everybody is doing it but if everybody jumped off a cliff and died would you follow just because you MUST follow after the crowd, the stupid decieved crowd? Please make an offline maual and attach it to the packed release.
