Hello!First many thanks to the developers for this great CCK! In our company we're currently building a website based on K2. At the moment we're using K2 v2.2 and Joomla! 1.5.13 (will be updated when finished and new website online). We started with K2 v2.1 and added with this version all tags. As I was controlling the tags after updating to K2 v2.2, I noticed that all tags which contains a dash (-) are listed a second time without a dash. If I want to save a tag containg a dash, the dash will be stripped.Has anybody an idea how to fix it?Many thanks in advance

Hi. We took this decision because there was a problem when using tags with dash and SEF URLs. When a tag contained a dash then the SEF URL was something like : /blah/blah/tag-with-dash. The problem is that Joomla uses the dash character to define the id and the alias in a URL. For example a URL to a K2 item or a com_content article is something like this: /blah/blah/id-alias. So the problem is obvious. Any tag with dash is split by Joomla and this leads K2 to have problems getting the tag from the URL.

Ok. I understand that point. I already changed all Tags. Thank you for the information!

It would be great if tags could have a "for display only" text field, and an Alias field. 

For words like "e-learning", using the dash is the only proper spelling. Leaving it out looks unprofessional (for my site, anyway). I don't have to have the dash in the alias, just in the tag that gets displayed on the page.

I managed to get around the issue by using  the n-dash HTML element: –
