I just wanted to post a quick calendar guide so everyone knows how to use it properly.
Click on the "Calendar" link on the top menu. This will open the current months calendar of events. The current day will automatically be selected (a red outline) as shown below:
The calendar is divided up into boxes with a short list of the events scheduled for those days. If you would like to see more information on a specific day simply hover your mouse over the appropriate day and click on it as shown below:
Clicking on a calendar day will display the form shown below. From here you can modify events you created, add new events as well as signup for events. To create a new event simply fill out the add event form and click on the submit button. To signup for an event, click on the signup button.
After you have clicked on the signup button, you should see two forms, as shown below. The first form will be the signup list. This is basically a rundown of all the signups for the particular event. It also allows you to remove your own signups from the event if necessary. Under the signup list will be another form, the actual signup form. This form is very simple, just select the character you would like to use from the list and click the submit button. You can also include a few quick notes if you would like.
As mentioned above, before you can signup for events you must claim your LOTRO characters so they are bound to your guildlaunch account. To do this click on the "Kinship Roster" button on the top menu bar. Search through the list of characters and once you have found one of your characters click the "Claim" button as shown below. Another form will pop up asking you to verify whether the character is actually yours. Simply click "Yes, the character is mine". You should now be able to signup for events using your claimed characters.
