Gave up finding the pros, messages of 70 characters only, easy to write messages, copy paste :)
Kontras
First of all, it toke me more then 2 weeks before i finally could fill in the contract and having the job. No training or help was given, only a guide i had to sign, anyway, At last, after a few emails i received my NLD number and login. Any questions i had took days to get answered by my contact who is rarely online. Which is way different with others i applied. Also, in the corresponding emails there was an overview on how much i could earn. 100 messages an hour was good for 1500 euros a month. Promising like the fast typist i am, yet in practice i could not even do half an hour, due... no messages. Now, after 2 weeks i finally gave up trying. Happy to say i found better.
