The Custom Template Tag collection includes the following tags:

e.g. Display if the owner (person who added record) of a profile IsOnline.

Buck's Review:

When working with XMod applications we were constantly searching for small enhancements that inexpensively helped us create top notch applications.

With Custom Template Tags we can know offer our web clients some of the features that were not included in XMod out of the box.

These tools are especially useful for DNN Professor Business Directory users who are selling listing subscriptions. Now your client can evaluate their subscription renewal by comparing the listing view count and number of ratings and comments.

Here is a live demo of custom tags in action.

I highly recommend the product to anyone using XMod.
