For an avatar your picture will need to be a 70x70 .gif file. Most photo editing software packages will give you the option of saving your image as a .gif file.
For help with your avatar question send a PM to Loss as he suggested today in his post under Avatar Clarification.
You can send PMs via the "My Account" link in our horizontal menu under the PT sunset page banner, the "Messages" link, and the "Create New Message" link that will appear in a box next to the Poll. Choose the member name from the drop down list, add a subject, write your message, and submit it.
So send me a message and I'll glady help you out
Oh yes, Welcome Marco
And do take Loss's invitation, he helped me very much when I was absolutely new and quite lost in Middle-Earth.
Have a happy journey, hope to meet you again and again on one or the other of the roads.
I know you'll have a great time joining the fellowship
