Searching tagged content in TechScreen

I have tagged content in TechScreen (solutions, challenges), and after some time now want to get an overview. It should be possible in a simple way to browse content in Techscreen by - getting a list of all tags, or my own tags - selecting one of this tags and get a list of the content having a certain tag Currently I see only the possibility to select a tag from the tag cloud (which is very large).

Track content usage

Having some stuff on the internet means that other people (or more commonly: the computer programs of other people) copy that content. This might be bad for you if you are worried of the specific copyrights or loose revenue. This might be good if you want to distribute information. However, in both ways you might be interested in who is copying this information from you. Some sites might hotlink or embed your content in their websites (e.g. this might be the case when it comes to images). You can typically detect such things in the logs of your webserver or your web analytics tool.
