[Enigmail] and for my first mistake...

[Taum Hanlon]

I first generated a key using RSA 4096 and then read that I should use 
the default DSA/ElGamal ... so I got rid of it and generated the type 
recommended in the FAQ.
...and I published it to pool.sks-keyservers.net

I have a question regarding setting owner trust and signing.
If you trust somebody and sign their key, the manual says it is good 
etiquette to send them the new signed key and allow them to upload to a 
key server.
Does this mean that everytime your key is signed you need to upload it 
to a key server to have that signture?
Also, can a key be signed by multiple people before it is uploaded to a 
key server?  (I'm wondering how 'key parties' work)
