First of all: thank you for reporting a bug instead of ditching the tool altogether. Every bug report is taken seriously and I appreciate your input.
If you find a bug, please take the time and see if the demo site is also suffering from this bug. Include as many log files and details as you think are necessary. Bugs have a lot of priority!
If you see a spelling error, grammatical error or a weird translation in your language, please join the CrowdIn project. There you can submit your translations and fixes. The GitHub repository will download these automatically and they will be included in the next release.
