Have you heard of prog that allows you to take control of your office PC from home? Yes, very cool and very useful but they want to charge you for it. Much better, then, to find an alternative which is just as good, just as secure and absolutely free! Yes, I thought you'd agree... here it is.
As a general rule of thumb, the best thing to do if you're searching for a program to do something and you don't want to pay for it, is to look for the 'open source' programs that do the same thing. How about a video editor? Do a search on 'open source video editor'. That's just one example. Most of the time, there's a free, open source program to do the job you need doing.
Oh, and while we're talking about searching, how about a search engine that's just as good as... the one that everyone uses... and contributes to the non-profit of your choice - with every single search. It's called GoodSearch. Enjoy!
