Whilst it is accepted that English is neither the "best" or the most commonly used language.
It is usually understood that most internet activity is conducted in English unless there are very good reasons to use an alternative language.
Unfortunatelty the above thread on a "help site" is not in English, & so is probably of no help whatevet to some 80% of the general population.
I urge the hosts of this site to allow only psotings in English.
