Years ago, I thought several things about open source and FREE programs.
Can't be as good.
Can't be as safe.
Must be cobbled together.
Or still under construction and not ready for prime time.
Or full of ads/spamware/scumware that pays for the program.
I was wrong.
So far I have had wonderful results with several free programs and scripts.
Rarely do I find one that disappoints me with yuck in it. (I read reviews/comments from other users before downloading).
SMF is one of those that gives you A LOT! And I am thankful for all the people that contribute to the program! Glad to spread the word about it. It may not fit for everyone. But it fits my needs just fine.
