How does e-mule work best for this site?

[superferret33]

Hi guys, newbie to this site here and also to e-mule.

I think I could fulfill a few requests. I have a couple questions about e-mule:

Am I supposed to use the program called e-mule to download the ed2k links? Or another program maybe?

If I try to download links that were posted over 10 years ago, how long should I wait to see if it still exists? Like a week or a month maybe?

Lastly, sometimes I have e-mule running but clicking on the link opens another e-mule, so the downloads split up into two e-mules? Is this some kind of bug or normal?

Thanks a lot
