Hi guys,
I appreciate your opinions, and we take them all on board.
This is essentially an experiment, if it works we'll look to do it in other languages too.
We chose Polish as we have quite a few members of staff whose first language is Polish, who suggested the idea in the first place, and have committed a fair bit of their spare time to launch this project.
We don't have any Welsh-speaking staff, otherwise I'm sure we'd have a Welsh portal too. If anyone who speaks Welsh would like to come and work for us we may give them a bit of work to do in that area!
IMO offering things like Tech Support in Polish will encourage people to join communities, by giving them access to things like study websites, and join groups which interest them, which in turn will encourage them to learn English.
If someone wants to move here but not learn the language etc, let's not pretend that our portal will change that person's mind, nor will it persuade people who do want to learn these things not to bother.
