Reserve for what?for this?
You should stop angry my friend. Maybe applicants confused with OP title (CFNP) and OP contents ( 10 open slots for Full Members and Senior Members). I think manager should ask the owner to edit OP contents a little bit, then everything will looks better, and we might see less non-sense applications.
The thread title is not confusing, people are sometimes lazy to search for the meaning.
FYI, CFNP stands for Closed For New Participants. You can also check this thread
