Hello Albert, welcome to the discussion!
There's nothing wrong with using FREE software if it does what you want. I've spent thousands over the years on live chat software, and at the end of the day LiveZilla does what I need for myself and 10 other staff. There's a few things I'd like to see extra, but nothing that we can't live without.
So, what makes "wglivechatsoftware" better than other live chat software discussed? It certanly can't be the reputation as you mentioned as the program has very little following. Only 7 sites currently link to the site. Searching for those mentioning "wglivechatsoftware" and there's 129 results most of which are your own pages.
The domain "wglivechatsoftware.com" was registered on 12/30/2009, so it can't be the years of track record that you're referring to as the domain is only 1 year old. So what makes "web greeters" more reliable and a better reputation than other products?
Why don't the "compare" or "buy" buttons on the main page of the website work? Is this an indication to the quality control put on the product too?
I tried to find a pricing sheet on the site - couldn't find it. All I could see in the header was a $100/seat/month fee. So $1200 and I don't own the software. For me, that'll cost me $12,000/year to operate.
Would love to hear more information on the product, but the site is hard to navigate and links don't work.
