When i create a synt, and enter more than one line of tekst in the comment field,
it will show the code for enter, and not doing it, on the webpage.
Exactly. This is the same issue that I reported here: http://photosynth.net/discussion.aspx?cat=a6bad539-de7d-4a16-8c4d-b143f7d5f984&dis=4340f65a-06ec-4ebb-a7cc-a19fd9e9a489
Nathan? Jonathan? Is anyone hearing this?
Yup, this is a known issue with the encoding of non alphanumeric characters between the synther and the website. We're working on a fix right now. In the meantime you can easily work around this by editing the description from the website.
