MultiPing is developed under the trialware (or shareware) concept. You're probably familiar with this. You can try out the software for a limited time (30 days) after which you need to pay for it.
MultiPing is completely full-featured for the first 30 days of trial mode, after which it disables one or more features (including Alerts, and possibly other features).
A license key will immediately convert the trial version of MultiPing to a fully licensed version. All distribution is done electronically for fast and easy access.
The easiest way to order is by visiting our web site at http://www.multiping.com/order.html. This site has all pricing and ordering instructions. Volume discounts are available.
