First you must be a member of SC Website, not just Guild Launch.

The best way to see if your a member is on the main page, scroll to the bottom and look at the left corner, if your name is there then you are signed in. (Note you could be shown as logged in at top right corner but not in bottom left, this means you are a guild launch member but not SC website member.)

If your signed in at top but your name does not show in bottom left corner then you need to join SC, go to the right and click Apply to Kinship. Fill the forms out, ignore the Launch Code.

After you are done you need to let a Officer know and they can activate you.

Once you are a member and your user name shows in the bottom left corner after you log in, you will need to add your toons,at this time both freep and creeps can be added.

Go to the top right corner, click your name, on the next screen you will now see some tabs, 2 rows, look at the second roll and select characters.
Here you will see which toons you have all ready at site or other sites or none at all. You can add current toons to SC and claim them here or claim them later through the roster page.

If you need to add a toon, click Add Character hyperlink just below your name on the tabs above the page.

Next you will get boxes to fill in, if you are lvl 105 or close, let a officer know and they will set that toon as raid ready but first you have to claim it. Make sure and let the officer you contact know the name of the toon you added and your user name at site.

Ok now you can sign up for raids, there is 2 ways to do it, you can use Rapid Raid tab on main page or use the calendar, both work in a similar fashion.

The calendar is easier to see what raids you would like to join.

So i'll use that way here;

Click calendar in the main set of tabs, then find the raid you want to join and click on it.

Next you will see a new window with that raid , click on the hyperlink in that page that says Signups.

Now you will see the information on that raid, who's signed up and with what class's, some raids are class specific, if your class is taken please still sign up as that person may not show and you would be next in line.

(Raid leader of that raid can view sign ups by date.)

Now to sign up, you can click Available , Tentative, or Unavailable on the right, click 1 then you will see a pop up window, select your name from the drop down and click submit, you can add a note here like " I can also take hunter".

(You can remove yourself or a character to change it to another through this way using Unavailable.)

Now you should be signed up, try to be in game on the toon you signed up with 15 min. prior to raid time.

The raid leader may have to move people to specific toons due to others not showing, so be patient with them please.
