I am an Estate Manager on the Realm of Usk and this player can not enter our land, oona.riaxik,

She is not on the Ban list of any estate here. Please advise me as to how to get her on our land.

Thank you,

Perri,

We are just volunteers here in Answers.

Assuming all age related criteria [avatar & real life] are met, then your player will need to open a Support Case with LL.

Perhaps you have the exact no access message they are receiving so we may advise you further.

P.S. Important - please edit your question and remove the avatar name you included.

P.S.S. Oh Well - Since we have her name I looked up her profile and don't see any particular reason for her to be banned from your G Rated Region. We'll need the exact access denied message she is receiving.
