I want to know how to add more than one tag?

And other question, where can upload a picture for avatar?

The first question is Solved!!
"Separate tags with spaces"
And who can answer the second questiom...m(_ _)m

In every post there is a link at the left called "Set Avatar" click it then you mark the part you want of the image, then you're done

So only the cartoon pictures is possible to use?

well, any post from moe, there are many

OK!!Thank you very much, have good dayo(∩_∩)o!!
