Join ur on http://mining.bitcoin.cz!EDIT 27.12.2010: wiki page about pooled miningIf you have a slower computer,... then pooled mining may be the only way that you will ever mint any bitcoins at all.
How do I get started?You need less than 10 minutes to start mining in pool. Visit
http://mining.bitcoin.cz and follow instructions.
I fit in to this boat but for the life of me can't figure out how to use these "miner programs" to contribute to mining.bitcoin.cz

p.s. I'm currently not generating coins. I use windows xp. I have an IBP p4 think center.
Pretty much wasting your time to put in simply.
But if you want to do it anyway, download the poclbm GUI miner which will come in a .7z archive. Extract this to a folder of your choice, then run the guiminer.exe file. Go to File>New Miner and give it a name. Then enter mining.bitcoin.cz for the server address.
Go to mining.bitcoin.cz and register an account, and then make a miner (It's under the "My Account" page, just click on "Add new miner".
Now back in poclbm under the new miner you just made, enter the username and password for your miner. This can be found under the my account page on mining.bitcoin.cz.
The go to File>Save Settings, and then start the miner. It will say in the bottom right how many Hash/s you are doing.
