How or where to post instructional videos for a fee?

Good luck with that mate.

Software would probably be your best bet.

You could create a file that expires with winrar perhaps and when they purchase..

You email them the file. Never tested that option though.

EDIT -> It was not Winrar.. It was APMB..

Some Features of APMB:

"Allow set an expire date to menus"

"Unlock expired menu with an unlock code"

"New option for menus, Allow Continue When Expired"

I've tested alot of programs over the years, I sometimes get them muddled up :)

I did find this doing a google search..

But is there anything stopping them from sharing the link?

Hope it helps :)
