I've been on the ICO website and still unsure of the rules around this, and hope someone here can help 
I'm in a FB support group and almost on a daily basis, posters ask for recommendations on services. I thought it may be helpful if I invited group members to send me their recommendations which I could collate in a spreadsheet.
This spreadsheet would only be accessed by myself in response to a specific enquiry.
Would I be falling foul of any DPA/information legislation?
