BTW: Your key 0xD5EF252D appears to be an ordinary DSA/Elgamal 1024 key with 
three UID's and unlimited expiry - is there are reason you've put the 
location of the key in the comment field of your email but not put the key 
onto keyservers? It means that to verify your signature, I cannot use 
auto-retrieve as you can to verify my signature. Some people justifiably 
don't use keyservers when they use signing subkeys and other features that 
older keyservers tend to not understand, but keyservers are useful things and 
it will increase the availability of your key. Keyservers are there to make 
it easier to manage key signatures that will prevent this message:

But none of those people have also signed your key. Key 0xD5EF252D has only 
been signed by you. Nobody else can therefore trust your key - we'll all get 
the same message on your key as you do on everyone else's key.

See some of these sites on keysigning:

Because you have signed your own key. Until you also sign someone else's key 
and someone else signs yours, you won't see any changes. 

You will always get some keys that are not certified by a trusted signature 
but the more signatures you make and the more signatures you receive, the 
more trusted your key becomes.
