Do not post your e-mail address here. Nobody is just going to give you an invite for this site that doesn't know you, so here is how you can get one. Its relatively easy.
Just follow these steps

Summarized...
Get an IRC client for mac or windows. just search google for one. i like Colloquy for mac.
Second, join the IRC server
irc.what.cd port
6667
Then, enter the channel
#what.cd-invites
In that room there is a link for instructions. Read them if you know nothing about music codecs, bittorrent etc.
Then go to speedtest.net and save the link from your results
When your ready... post this in the chat room
!queue (speed test link here)
You will then wait until they invite you into a room to answer 25 easy questions.
Then they will probably invite you.
