I noticed Dan Grossman posted a link to Helpjuice.com
I'm the founder of Helpjuice.com, if all you are looking for is ONLY a faq/knowledgebase, then I'd suggest you dive into Helpjuice.com deeper.
However, if you're also looking for ticketing, fb+twitter support, phone support and all that other good stuff, some of ou competitors might be a better fit.
Some feedback:
1) I went to sign up for a trial and noticed that there was no https on the submit form. Unfortunately that's a no-go since the password is transported via plaintext unless I'm misunderstanding something. This is the only real deal-breaker. 2) The price-point is a little high (not a deal-breaker), but I didn't really get a chance to test-drive the product because of the lack of https. 3) I'd like to keep branding on faq.mydomain.com
You're "We're helping" counter currently shows 1,444,500 and counting. I clocked it increasing at approximately 16/second. That would mean it would hit 1,382,400 in a day. Which means it just started yesterday? Or does it just reset after 24 hrs or something?
$.get(url, function(data) { max_help_count = parseInt(data); help_count = max_help_count - 5000;
and the url it seems to point to is: http://helpjuice.com/live-help-counter
