Comment 2 for bug 2975

Then you could discuss this in other forums, with the other translators. I think the goal should be to have one definite suggestion for each string.

Another possibility would be that you're allowed to add additional translations (through a "Add as new suggestion"-checkbox for example) but replacement is the default behaviour. As it is now, there is no way at all to replace your old suggestion, and I think you should be able to.
