Seed addresses when solo mining? (maxcoin)

[candtalan]

I am new to mining, and I am having a modest go with maxcoin solo mining. It looks like it is working, which I am delighted about. I am using Ubuntu and maxcoind, and a configuration file was needed maxcoin.conf which I see contains seed addresses. Do seed addresses 'wear out' or get used up? Is it a lot better to have a lot more seed addresses?
Comments would be much appreciated

Sry for offtopc, but could you help with solo mining config?
I've managed to run cgminer for solo, it looks working but doesn't show
"New block detected on network" or shomething like that.
Is it ok?
