While I have not used those programs and services myself. they appear to be more than good enough.
I have already posted about other ways of FREE (If you have a connection) instant Internet communication if you see my prior posts here at the blog, but there is even more comunications freeware if you can find it with a search engine.
I look at reviews before I post about programs and services.
I don't post about everything that I find, be it good or bad, but I do post about some (Not All) of the good stuff.
I think that by now I have shown all of those communication freewares that I am going to show for now and the near future. as I say I only show some of the best, but not all of them.
