Help us to improve OR Help us improve?
Well, probably the Ikea PR 'experts' got confused too...and that's why he / she used both 'Help us to improve' and 'Help us improve'. You should say and write "...help us improve...' or 'Fiona, please help me send this fruit basket to Dr. Chan's office.' or 'Miss Frances, please help me proofread my paper.' To avoid this 'Help me to...' problem, simply say or write 'Fiona, please send this fruit basket to Dr. Chan's office for me' or 'Miss Frances, please proofread this / my paper for me.'. Life is MUCH EASIER now, right? You're welcome!
