It needs about 3000 to 4000 helping points each month to keep the catalog up to date and someone has to do it.
I usually have about 1000 to 1500 helping points because I add many labels to the catalog or update the labels some one else has added with incomplete data and take 3000 of the mentioned points in total. To reduce my workload I set up the level when the trade lists are opening to 50 helping points. You can check WhatsApp, Social Media and FB instead of me and add everything what is new. Adding interesting comments or background information is also increasing your balance.
And - of course - you can buy helping points when you help in the IT cost or when you send me labels for my collection.
