What do you like best?
HL allows you to customize community groups and micro-sites for any purpose you might need. The HUG user community is also really awesome for learning how to make the most out of HL software and customize your site to accommodate members' needs.
What do you dislike?
Customization requires advanced coding knowledge, you're otherwise pretty limited with its basic templates/widgets to customize microsites and communities with their WYSIWYG module. It's easy to customize your site to have all changes apply to all communities, but difficult to customize setting for only one community on your site (unless you change it into a microsite). For blogging functions, unless you know code, the font size, colors, table formatting, image insertion functions are very basic.
Recommendations to others considering the product
Customer service involves a ticket system or posting on the HUG forum to get peer assistance on solving issues or finding innovative ways to use the product. Don't expect immediate responses on support issues; it would be nice to have 24/7 live chat support, but it doesn't work that way. Tickets usually receive a response w/i 48 hours.
What business problems are you solving with the product? What benefits have you realized?
We use HL to provide a community forum for members to connect, exchange info, and post/share content or blogs with each other. It also serves as an information portal for us to send out alert, blogs, etc. to members too. The file libraries are nice for sharing resources too.
