Open the menu under your profile picture and choose Account settings. A menu on the left, one section at a time on the right.
Two of these ask who can see you. The third asks what of yours they can find. Each row shows how yours is currently set, and opens to let you change it.
A resource also carries its own Public visibility toggle. That and the setting above both have to allow it before someone who is not signed in can find that resource.

Three rows — email address, phone number, address. Each opens for editing in place.
Your email address is where every notification, event email and letter goes, and it is how support finds your account. If you move institution, change it here first.

Every notice the platform can send is grouped into Peer activity, Communities, and Posts. Each row shows its channels — Email, In-app, or both. Open a row to change them.
Presenters: leave the comment notice on. It is how a question on your presentation page or discussion board reaches you.

Two things on one screen: whether you are available to be asked at all (and the number per year), and a toggle for each research network you are willing to read for.
Nothing on this screen is kept until you press Save.

Points and credits are not the same thing, and the screen says so at the top.
Neither is money, and neither converts into the other.

Two things govern this and both have to allow it. Check Resources visibility under Account & privacy, and the resource’s own Public visibility toggle. If the Add new resource dialog shows a notice saying your resources are not visible, yours is currently set to Hidden — the notice links straight to the setting.
If they are signed in, that is Profile privacy. If they are not, that is Profile visibility. Two separate settings, either one can be the cause.
Check that notice’s row under Notifications — its channels may have been narrowed to In-app. Then check the email address under Contact is one you still read.
There is a Save button at the bottom of the screen. Nothing is kept until you press it.
No. Points apply only in CGPublisher. Event registrations draw on credits, and the two do not convert.
They do expire. The date is on the CG Points card — use them in Publisher before it.
