I saw you have no Hive Power HP (staked Hive) which is needed for your account to work propaply, i think you can see it as kind of an spam protection.

To post something you need so called rc (ressource credits) which you get automatically when you have hive power.

Everytime you post some rc got pull off to prevent somebody create thousands of accounts and doing spam shit.

But rc regenerate itself so its nothing to worry about, its just from that spam avoiding perspective.

Therefore i delegate you a few HP so you should able to post a bit.

Here is an good guide with some useful information to start with:
