Soon or later I believe there will be more users as UNB getting popular . In that point of time, this will be really a matter as it is confusing to search trough the forum for information. As you said, now there are too few users. But how if then there will be a lot of user?
My sugestions is to set english as the standard for asking support. Then set up a special forum for support in specific language ( german, indonesia, etc ). This should be set as posting rules so that eveybody must obey.
It will be easier to sort out the posting and classified it now rather than waiting until the number of posts increased.
