henningl -> Any bugs that exists in both prosilver & subsilver2 will get fixed at the same time. Although currently most of what I am dealing with is prosilver only ... subsilver2 is much more stable. I currently & plan to continue to fully support subsilver2. So if your template is based off it you should be OK. To install just follow the subsilver2.xml in the ./templates/
Reminds me I must install & configure subsilver2 to the demo so you can see what it looks like.
If its highly highly modified you might have to spend a small bit of time to get sorted, but here I will help as much as possible.
If its a released template I will be accepting XML files to get included in the original package. This way you can contribute back to the MODification & the community
