The problem on joining the slack workspace of iceberg

[Pao.s]

Dear All,

I am interested in the project iceberg and want to join the community.
But I don’t get the invitation when clicking the link 
(https://s.apache.org/slack-invite <https://s.apache.org/slack-invite>) on the 
iceberg community website (https://iceberg.apache.org/community/).
I look forward to your reply.

Thank you,
Pao-Sheng, Wang.
