In order to keep track of all issues surrounding our tool, we have set up a bugtracking tool here: http://bugs.galaxytool.eu/main_page.php .
You can open issues even if you are not logged in (we hope we can keep this open without spam). Please do not open an issue as long as you are unsure if there is actually a bug involved. Unless your bug is obvious (e.g. in translations), dicusss the issue on the forum first. Flaws and typos in translations are now exclusively handeled in the bugtracker. If you want to get email notifications of issues you are interested in, please register first.
