Arggh!

I've been searching the net, trying to find the latest patch to the kernel, and I'm a litlte confused ... I checked out www.kernel.org, and they list alot of versions that are beta, pre-patch, blah-blah ... that confuse this young grasshopper

So, the question is: I have kernel version 2.4.18-3 .... now, what is the latest patch(s) to this that are stable?

The reason I ask is not becuz I believe i need the latest patch, but becuz i want to get practice installing one when the time comes when I actually need to know how ;D Gotta teach myself Linux somehow!
