You can speak directly to the Grid Owner, Starflower Bracken, through public chat from anywhere on the grid. If you want a more virtual world experience, please go to one of the enquiry centres, the Beach Bar on Annwfn, either the Quay House or the Harbourmaster's Office on Celyddon, or the main bar of the Merry Maids Inn on Gododdin and, as if by magic, her avatar (or rather, an NPC representation of it) will appear and she will speak to you through it. Please be patient if you do not get an instant response but be assured that Starflower (or Star, if you prefer) will be doing her best to be available. Sometimes she may be busy, working or using a phone to type! You don't need to be in one of these specific locations to get in touch.
Please say "Starflower" or "Star" in public chat to increase the likelihood of being immediately noticed on the in-world chat.
Public Chat in OpenSim
Public chat on Ocean Grid is not publicly viewable on any internet channel, given the potential privacy implications: nobody within an OpenSim region would be able to see who is logged on to the chat channel and therefore cannot know who is listening. Only administrators are able to see public in-world chat via a private IRC channel. It isn't normally recorded unless a suspected breach of TOS is being investigated (which has never happened on Ocean Grid to date).
Use private IM or group chat if you want greater privacy, as this cannot be heard even by administrators.
