The meaning of "meaning"

I'd like to know the meaning of "meaning" in the following sentences:

Please note that we have implemented a 1 post approval process for new users. Meaning, a newly registered user with no posts under their belt can post, but will have to wait until a moderator approves it before it shows up.

Solution 1:

In the above sentence "Meaning" is used as a participle. You could replace it by: That is to say/i.e.

Solution 2:

Please note that we have implemented a 1 post approval process for new users. Meaning, a newly registered user with no posts under their belt can post, but will have to wait until a moderator approves it before it shows up.

expands to:
