Knowledges ≫ I can't read some messages sent to me, why is that.

Depends on your membership level.
VIP members can send, read and reply to all members messages
Free members can send, read and reply to VIP members messages
Free members can send and reply to messages from free members.
So if you always want to use the site for free only contact VIP members, this is the VIP ADVANTAGE, because VIP members have fully access to everyone and that person (Free members) have full access to ALL VIP Members, but not to other Free members.
